Talk:Calliphora vomitoria

Page Move

I have moved the page from Blue bottle fly to Blue Bottle Fly as it looked messy before and other creature have capital titles Gaogier ^{How can I help?} 10:47, 6 August 2008 (UTC)

Ah yes, but now it stands out among the insects for having a capitalised name. Our guidelines are for arthropods not to be capitalised. --Stemonitis (talk) 08:06, 21 January 2009 (UTC)

Two problems with this article

1. The blue bottle fly is also the common name given to Protophormia terraenovae, which may mean either that this article contains incorrect information or at least needs to be disambiguated.
2. There is already a more in-depth article on the species Calliphora vicina. Does that render this page redundant?

I'd be happy to fix this article if I knew anything about fly biology, but I don't. 70.129.149.116 (talk) 19:28, 7 August 2010 (UTC)

For (2), it turns out someone changed the species name here from C. vomitoria to C. vicina, so that's probably why you thought we had two different articles on the same fly species. For (1) that's probably a good idea too. howcheng {chat} 09:38, 15 August 2010 (UTC)

Feeding habits

In the introduction it is stated:

   Blue bottle fly adults feed on nectar

whereas the Life Style section has:

   A female blue bottle fly lays her eggs where she feeds, usually in decaying meat ...

which seems inconsistent? quota (talk) 08:41, 19 January 2013 (UTC)

A female bluebottle requires a protein meal (meat) for her ovaries to develop and her to become fertile. Many flying insects, including female blow flies require a high sugar diet to provide the energy for flight. Thus they eat more than one thing depending upon their requirements.

A Separate Page for Calliphora vomitoria

This article has been written as if the term blue bottle fly was synonymous with Calliphora vomitoria. This is incorrect: C. vicina has just as much right to be called a blue bottle fly as is C. vomitoria, and there are probably several other species of Calliphoridae from around the world for which the same could be said. Also, the term 'blue bottle fly' is relatively fuzzy (how greenish does the blue have to be before it becomes a green bottle fly?) while, in comparison, Calliphora vomitoria is relatively precisely defined. Conflating the two terms on the same page is only likely to confuse readers.

It would be much better for Calliphora vomitoria to have its own page and for the Blue bottle fly page to clearly list some of the species (C. vomitoria, C. vicina, at least) that are regarded as blue bottle flies.

Images Incorrect

2 of the images at bottom of article appear to be Green bottle, ( Lucilia sericata going on Occiptal Setae), so should be removed. — Preceding unsigned comment added by 80.3.70.176 (talk) 20:29, 2 June 2014 (UTC)

The images to the side and at the bottom are both Calliphora vicina. Spot the pale basicosta in the top image and lack of orange bristles behind the jowls in the bottom image.

Etymology

Clearly the "blue" part refers to the insect's colour, but where does "bottle" come from? Zacwill16 (talk) 20:48, 27 June 2015 (UTC)

• "bottle" is cockney rhyming slang for "arse", via "bottle and glass". "Blue bottle" refers to the iridescent abdomen. Paul Murray (talk) 04:39, 24 May 2017 (UTC)

Assessment comment

The comment(s) below were originally left at Talk:Calliphora vomitoria/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

== Blue Arsed Fly? == I actually got to the article by searching for blue arsed fly - I was looking for the origins of the expression, and while I suppose this answered my question it makes no reference to the very common idiom which is derived from this creature's frantic pace. Perhaps a footnote or a link to a page on slang? —Preceding unsigned comment added by 130.102.44.13 (talk) 01:37, 3 October 2007 (UTC)

Name

Is "blue bottle fly" a common name for this insect? I've only ever heard it called a "blue bottle" (which would imply that per Wikipedia convention the article should be "Blue bottle (fly)") Iapetus (talk) 15:29, 30 January 2018 (UTC)

Behavioral Ecology Comment

For my Behavioral Ecology class, we are reviewing Wikipedia articles on flies in the order Diptera, and I read this article for one of my pages. The entry goes through a brief description of the life cycle of the blue bottle fly and has several closeup images of the fly in the “Gallery” section. The blue bottle fly can sometimes cause human/animal myiasis, and the female fly lays her eggs in decaying substances (where she feeds). The article is concise and has nice visuals, but there are several components that could be added to improve the article’s completeness, such as sections on the fly's ecology/habitat, evolution, and biology. RappaiT (talk) 00:09, 18 September 2019 (UTC)

As the writing expert for this class, I recommended and fixed a few key parts of this article. I changed the spacing between sections, took information out of parentheses and put it into complete sentences, and fixed some grammatical and tense issues. Overall, this article is well written and has good information.Hannahwhite97 (talk) 02:56, 29 October 2019 (UTC)

Peer Review

I did not find too many problems with the article! Very clearly worded and understandable. The edits I made mainly consisted of cleaning up sentence structure and hyperlinking additional terms.

I believe the last sentence of your description (Similar species include the greenbottle fly, a close relative that can be distinguished by its bright green metallic coloring.) needs a citation. Additionally, your sentence in the “egg” subsection of the “life cycle” section needs a citation.

andrewoh29 (talk) 21:26, 1 November 2019 (UTC)

One of the first things that caught my attention in this article was the great use of photos throughout the article. One of the changes I made was a rephrasing of the description of this fly in the introduction section. I also swapped out some of the words used so that the sentence structure was more grammatically correct. I think that you should be providing more citations in the introductory paragraph, or also including links to some of the terms used, such as oviposition. I think there is great room for improving your life cycle section as I think the current information you have in your article is very broad and could be the case for a large number of organisms in the Diptera order. I moved your subheading “Stages of Decay” up from under the heading titled “Food Resources”, because I didn’t think these were really related to each other. I think that this subheading was better fitted under the life cycle section. Another detail I changed was lowercasing all of the terms after the first word of each heading, in order to keep this pattern consistent throughout the article. One last suggestion I have is in regard to the captions under each picture in your featured photo gallery. I think that including the source of the photo, as well as being a bit more thorough in your description of what is happening in each picture, rather than being colloquial, could serve as one more enhancement to your article’s overall appearance. An interesting section of this article was the Forensics subheading, in which you elaborate on how Calliphora vomitoria behaviors actually contribute largely to human studies and examinations of forensics. This was really cool. 06:59, November 5, 2019 lelandra

Blue bottle fly → Calliphora vomitoria – Imprecise; other calliphorids are also known as blue bottles/blue bottle flies, such as Calliphora vicina, Protophormia terraenovae, and possibly others. — Hyperik ⌜talk⌟ 16:19, 10 November 2019 (UTC)

@Hyperik: so then Blue bottle fly should become a disambiguation or set list? --Nessie (talk) 15:36, 11 November 2019 (UTC)

I'd agree with Plantdrew to just redirect it to Calliphoridae. —Hyperik ⌜talk⌟ 04:35, 12 November 2019 (UTC)

Lead

• or bottlebee is a common blow fly, a species in the family Calliphoridae – since "common" is again mentioned in the next sentence, I suggest the simpler wording "or bottlebee is a species of blow fly (Calliphoridae)". This also makes clear that blow flies and Calliphoridae are the same.
• It is relatively common throughout many widespread regions throughout the world. – Perhaps "It is relatively common in many regions of the world"? Otherwise I don't fully understand it.
• When reading the details in the main text, "relatively common" seems to be an understatement (why not just "common"?), while "many regions of the world" seems a bit much, as it is not a cosmopolitan species. Consider mentioning the occurrences as done in the main text.
• the blue bottle fly females deposit their eggs on rotting corpses – just "femals deposit their eggs …" is enough, no need to state "the blue bottle fly" here, just makes it difficult to read.
• oviposition – I would link this term, as not everybody will be familiar with it.

Main text

• thorax, abdomen, tarsi, hibernate, salivary gland are terms to link if possible, to make the article as accessible as possible.
• I miss an important practical information from the description section: How can the species be differentiated from related species? What are the diagnostic features? Is identification possible based on simple photographs, or is microscopy needed?
• The pupal stage is the longest stage before they emerge. – before the adult stage? Does that mean that the adult stage is even longer? Could be made clearer.
• the adults emerge to mate – you mean they emerge from the pupa?
• At the beginning of metamorphosis – I assume during the pupal stage?
• Then, on day 9, cell death occurs. – cell death of what? Of the whole fly?
• The paragraph on the apoptosis is not easy to follow. Maybe focus on describing the precise life cycle of the fly first, and only then explain what this means for the assumption of adoptosis = programmed cell death.
• How long does the adult life?
• it has been shown that when processed substrates, such as beef and turkey, – but beef and turkey is not necessarily processed? With processed you mean cooked?
• rather than unprocessed substrates such as liver – liver can also be processed food? What is the difference to beef and turkey?
• C. vomitoria is best characterized as a specialist. – A specialist on processed foods? On what it is specialised naturally?
• Growth rates between surface and buried larvae grew at a similar pace – maybe use "increased" here?
• the fly larvae leaves the carrion can burrow into the soil in order to pupate. – is a "that" missing? "The fly larvae that leaves"?
• C. vomitoria shares carcasses with other species such as – with other calliphorid species?
• Reference 21 is not working.
• They mainly pollinate skunk cabbage (Symplocarpus foetidus), American pawpaw (Asimina triloba), dead horse arum (Helicodiceros muscivorus), goldenrod and some species of the carrot family – Not sure about this statement; the mentioned species do not occur over the whole range of the species. Maybe write "plants pollinated by the fly include …" instead of "mainly"?
• more later. --Jens Lallensack (talk) 22:46, 15 January 2020 (UTC) Forgot to ping @Y.shiuan: --Jens Lallensack (talk) 07:44, 16 January 2020 (UTC)

@Jens Lallensack: Thank you for the many thoughtful suggestions, I'll keep working on the article Y.shiuan (talk) 01:21, 20 January 2020 (UTC)

@Y.shiuan: As month has passed, I just want to check where we are standing? There is no deadline, though in case you need much more time, it may be better when I close this nomination now, and you nominate again when you are done. In the latter case, I can offer to take on the review again, so that we can continue where we were. --Jens Lallensack (talk) 20:32, 21 February 2020 (UTC)

@Jens Lallensack: Hi! Sorry, I had a very packed beginning of the semester that recently let up. I've been working on the page in small bits in the last week or two, and I am still working on it now that I can dedicate more time to it. I would still like to continue with this current nomination if that's fine with you? Thank you so much for reviewing it and for being so patient! Y.shiuan (talk) 00:49, 24 February 2020 (UTC)

Cool, glad to hear that! Take your time. --Jens Lallensack (talk) 06:29, 24 February 2020 (UTC)

@Jens Lallensack: Hello! Sorry for the delay, but I think I've covered everything you suggested so far. I did have difficulty finding info on how long the adult lives (papers seem to focus on life cycle up to adult stage). Y.shiuan (talk) 17:24, 4 March 2020 (UTC)

@Y.shiuan: Some more now, more later:

• Calliphora vomitoria occurs in most of Europe, Alaska, Greenland, the south of Mexico, Virginia, Hawaii, and southern Africa – Why is the distribution so fragmented? They only occur in Virginia but not elsewhere in mainland US? Cannot believe.
• Blow flies like C. vomitoria lay their eggs at carrion sites, which are scarce in most places so they end up with lots of eggs on corpses, laid by different species. – not an ideal sentence, since it is not clear on what "they" is referring to. The corpses? The bow flies? Maybe more precise: "which are scarse in most places and so commonly contain eggs from multiple individuals of separate species" or similar?
• likely because of contact and chemical stimulation – after "because of" I would expect to hear the "advantage" of having increased oviposition. Maybe "triggered by" is more precise here?
• increase oviposition – do you mean they increase the speed of oviposition? "Increase oviposition rate" or something maybe?
• The large number of larvae, though, actually ends up being beneficial in the group. – Also not ideal. We don't need both "though" and "actually". "In the group" is redundant with "the large number of larvae", or do you mean "for the group" (which also does not make sense)? "For the individual"? But then I would also add an "generally".
• One complication with these benefits – Not with the benefits, but with the high number of individuals.
• Its application to forensic science, stems from the idea that the time of oviposition can then be determined – I don't understand. How do you determine the time, you were only talking about day and night? Also, we don't need the comma I think.
• Section "Brain" – I think this is better named "Hormones"?
• at base of their 2 claws – at "the" base of their "two" claws?
• make sure there is no space in front of the citations. Example: "and it has been concluded that lateral pulls required much greater forces. [28][29]"
• The force of adhesion between vertical and lateral pulls has been measured, and it has been concluded that lateral pulls required much greater forces. – Can't follow this; with "much greater forces" you mean greater forces of adhesion or stronger pulls? --Jens Lallensack (talk) 19:48, 4 March 2020 (UTC)

@Jens Lallensack: Done! Ready for the next set Y.shiuan (talk) 17:12, 9 March 2020 (UTC)

• to conclude that lateral pulls required much stronger pulls – this still does not make sense. Pulls require pulls? Require to do what? To displace the insect? If so, maybe just mention that.
• "forensics" should be linked at first mention
• These flies are among the most important insect evidence in forensic science.[14] Calliphora species in particular – I don't understand the "in particular". That suggest that a broader category was mentioned previously. But "these flies" can only be refer to the topic of the article, which is a single species.
• the time since eggs were laid – "when" the eggs where laid?
• In addition, C. vomitoria has higher threshold temperature than many species; likewise, it is present in many regions. – Is this about climate or corpse temperature? I am confused.
• 35 degrees Fahrenheit – please provide °C as well.
• Carcasses are divided into several different stages – This reads as if carcasses are physically divided. What about "Degradation of carcasses can be divided into …"
• into several different stages – why not "into six separate stages"? Be as precise as possible.
• In buried corpses, the timing and how body was stored – timing of what? And: how "the" body was stored?
• how the body was stored can be collected – I don't understand, what is collected? Also, can this be more precise?
• through the identification of C. vomitoria in these substrates – why do we need "in these substrates"?
• The study of these flies, however, are limited to areas where entomologists are readily available, – "is" limited
• as each region may contain the same species but with different life histories – maybe "as life histories can differ in separate regions"? Would be good to have some information on how the life histories differ. Are these subtle or big differences?
• In order for C. vomitoria to provide useful data to investigators, these restrictions should be considered, so the proper time of colonization (TOC) and post mortem interval (PMI) can be established. – This sentence has three parts. The first part seems redundant with the third part and can be removed without loosing information I think.
• time of colonization (TOC) and post mortem interval (PMI) – as this seems to be the goal of the forensics (?), it could be mentioned much earlier in the section. Also: What is the post mortem interval, can this be explained or linked?
• Forensic scientists sometimes identify it in the course of their work – "in the course of their work" says nothing and can be removed.
• particularly in the case of an autopsy of a neglected child. – a single case?

@Y.shiuan: – only one section today, but I think this one really needs work as I found it difficult to read. Sorry for all the stop-and-go, but my time per day is currently quite limited. One more round and we should be done! --Jens Lallensack (talk) 20:05, 9 March 2020 (UTC)

@Jens Lallensack: Hi, sorry for the wait- I believe I'm done with that part! I ended up deleting the bit about the pulls because I couldn't really make sense of it either. Hope all is well for you with everything that's been going on! Y.shiuan (talk) 23:35, 20 March 2020 (UTC)

All good, thanks – hope on your side as well! --Jens Lallensack (talk) 11:51, 23 March 2020 (UTC)

• Some methods that can best differentiate between the species – "some" seems somehow in conflict with "best". If these are only some methods, these cannot be the best. I suggest to remove "Some".
• COI gene used in conjunction with the SfcI restriction enzyme – these terms need to be linked, and/or the abbreviation spelled out and explained.
• Post mortem interval (PMI) – suggest to remove the abbreviation (PMI) from the section heading and place it in the article text.
• C. vomitoria is important for PMI because – "for PMI estimations"
• C. vomitoria is important for PMI because they – "C. vomitoria" is singular, "they" is plural. Better "because it is among the first species to lay eggs" or similar.
• Another way to calculate PMI is to calculate accumulated degree hours/days (ADH/D) – I do not understand this.
• Calliphora vomitoria is considered one of the most important flies in medico-legal cases. – You already stated that it is important for forensics; what is the difference to "legal cases"?
• Calliphora vomitoria is frequently used as pollinators – this implies that it is cultivated for this purpose. Really?
• The flies feed on the nectar of these crops and then proceed to spread their seeds when they fly. These pollination events – seed dispersal and pollination are two different things!

@Y.shiuan: – that's it! --Jens Lallensack (talk) 11:51, 23 March 2020 (UTC)

@Jens Lallensack: Done! Y.shiuan (talk) 20:15, 29 March 2020 (UTC) @Y.shiuan: – Looks good, thanks! Promoting now, congrats! --Jens Lallensack (talk) 20:17, 29 March 2020 (UTC) @Jens Lallensack: Thank you so much! Y.shiuan (talk) 22:23, 29 March 2020 (UTC)

Dragonfly vision

Insects with compound eyes have a clarity of vision which is directly related to the number of facets in the eye. Each facet does not create it’s entirely own image each facet is more like a pixel so the more facets of the eye the clear the image.
