Pauline wrote:Thanks for your comprehensive reply Pete. I'm just a little bit paranoid that my PH are going to emerge a bit too early as they pupated a little while ago and are starting to darken. I'm kind of hoping that if the PE is early this year (as predicted) then perhaps the PH will also be early. Really just want to get it right but what can you do? Like your WLH they have been outside the whole time :?


Sounds like perfect timing - PH must be imminent! Silver-washed are out in some parts of the country and (in my head at least) these two species emerge together :)

Wow, that small Heath chrysalis image is stunning. The wall and gatekeeper pupa are impressive,too. As your excellent pictures show, the immature stages, in many cases, are quite as beautiful as the adult. Perhaps more of us would do well to focus a little bit closer on these stages.

Those early stage images are wonderful, Pete. You are putting a lot of effort into this and we all appreciate seeing the results.

Thanks all - the comments are much appreciated, even if I don't reply in a timely manner! Work has been brutal this year, especially the travel which just chews up time. Anyway - a few updates. As I've already mentioned, my focus for this year and next is observing the immature stages, so here are a few more snippets! I have over 2,000 images to process in the winter and many more to come, I'm sure!

I don't know how you do it Pete, I've basically had a 6 week holiday and I'm exhausted just from the butterflying, never mind doing the job on top of it!

Thanks Paul!

It is exhausting ... very exhausting ... but the results and observations (which are a pleasure to share) are well worth it!

Cheers,

More random photos - I currently have 2032 images to sort out over the winter ... but here are some I like :) All instars (where relevant) have been photographed and I can't wait to get to processing things! There will also be an exciting update regarding the descriptions of all of the immature stages soon - watch this space :)

Cracking stuff Pete - your images make the once considered 'boring' bit of the life cycle much more interesting :D

Pete, this is (yet again) really good stuff. I shudder to think what you will compile once you retire if you can conjure up stuff like this in between 'brutal' periods of work!

Roll on retirement (or semi-retirement even).

Thanks Wurzel, David!

White Admiral larval survey

Today I conducted my first survey for White Admiral larvae in Pamber Forest and found 16 in just over an hour, together with 7 absentees (based on the typical larval feeding damage and "pier"; I assume predated). Based on previous years, this is a pretty good "hit rate" and it would appear, based on this limited data, that White Admiral has had a relatively-good year. Most larvae are in their 2nd instar, with some still in their 1st instar. None are in their 3rd instar, so I don't hold out much hope for a second brood; the recent weather seems to have calmed things down considerably. I also found a final instar larva (I assume that overwintered in 2016/2017) that has been parasitised, presumably by Cotesia sibyllarum - the usual culprit when it comes to White Admiral. Amazingly, this larva is still feeding as per normal, despite grubs having emerged from it, where they have built cocoons, pupated, and a few emerged.

Other Stuff

As with all updates of late, here's a random set of images that will contribute to "Project Frohawk" - the last (Adonis Blue) seems to have gotten quite a bit of interest on Twitter and Facebook, although I can never predict how people react to such things!

Interesting you haven't found any third instar White Admirals Pete. I'm pretty sure I found at least one at Bookham last week (pictures in my pd) and think I found another one today which will be posted in due course.

Hi Paul - you did indeed find a 3rd instar! If the head capsule is brown, then it's 3rd instar: viewtopic.php?f=29&t=3977&start=940#p112980

I'll take a closer look if I get a chance to revisit this week!

Cheers,

Staggering pictures, Pete! Brilliant in every way - subject matter, timing and execution.

I concur with Guy Pete, staggering photos especially the Essex Skippers in the egg, looking a little like Frog Spawn :D

Amazing macro images, Pete. You are opening my eyes to the less commonly seen aspect of the butterfly life cycle.

The Adonis inside the pupal case is especially striking.

Thanks Guy, Wurzel, David, Vince! Things are definitely slowing down on the immature stages front, thank goodness! In the meantime, here are some updates:
