Project Frohawk

Postby Pete Eeles » Wed Jan 04, 2017 9:48 pm

This post is to make you aware of a new UKB project where Vince and I need your input and feedback. Around the middle of 2016, and after a discussion with Vince, it was decided to break out the various larval instars. And so, rather than there being a single larva section on the species pages, or a single album of larval images for a given species, each instar now has its own section (and album). This is a natural evolution of us having so many quality images of the different larval instars of each species. Although I'd implemented the mechanisms required on UKB shortly after that decision, it's taken quite an effort by Vince and myself to move all of the images into new albums (1 album per larval instar per species) and make sure they're correct, as best we know (and a huge "thanks" to Vince for putting in the incredible amount of effort involved). There are still quite a few images to be sorted, but we didn't want to wait until that was complete before announcing this project, since you may want to contribute in 2017. Also, we have yet to complete the description of each instar (which we will, in time!). Anyway, a good example is the Swallowtail (just click on the "Larva" twisty): ... es=machaon

In addition, a new page has been added (under Species->Life Cycles->Larval Instars): ... nstars.php

You can also see all of the gaps here (although a moderator will need to be told if you fill a gap, before this page updates, since the page is cached): ... tage=larva

So the question is - would you find this useful, and what can be improved?

Oh - and why "Project Frohawk"? Aside from Frederick Frohawk being a personal hero, his seminal work, Natural History of British Butterflies, is a 2-volume masterpiece, with exquisite plates, and the culmination of 24 years (from 1890 to 1914) spent rearing all of the British butterfly species and documenting the findings in meticulous detail (publication was delayed due to the outbreak of war in 1914, and later by insufficient subscribers). The work has never been surpassed and "Frohawk", as it is lovingly known, is still actively referred to today, especially by those wanting to understand the development of the immature stages of the British butterflies. However, some of the early instar images are very hard to make out (since they are drawn life-size) and so perhaps we can add some clarity in heading toward Frohawk 2.0 :)

Excellent idea, Pete.

I am becoming a fan of Frohawk myself having read June Chatfield's book of his life. Now, I have to fork out hundreds of pounds for his Natural History of Butterflies Vols 1 & 2 :)

Roll on March.

This will be very useful, Pete. More and more people are looking for larvae and identifying non-final instars from the books can be difficult.

I have a (very) few of the missing links, which I'll sort out as soon as I get a moment.

My congratulations to Vince and yourself (Pete) for carrying out what must have been a major task. It sounds as though you are filling a long-existing gap in the documentation of early stages.
