We published a review of the genus Strategus in Louisiana in 2018, mostly using the adults my wife and I captured over the past 55 years of non-stop collecting. Here is the link to a free access to that pdf: https://www.academia.edu/37938943/THE_G ... _LOUISIANA

Such a minor mark doesn't detract in any way from it being a perfect specimen.

Wonderful specimen indeed, congrats.

I would be very happy to have a super specimen like that, despite the tiny rub mark on the right forewing.

kevinkk and Trehopr1,
Thank you both for your words of consolation.
P. rutulus is a pretty common butterfly in CA,
I hope to get more in the future.

Trehopr1 · by Trehopr1 » Wed May 15, 2024 9:51 pm

That is a picture perfect example in my humble opinion.
You should be very proud of its exceptional condition.
Well done....

If it wasn't held so dang far away (for most of us on the Eastern seaboard) and the traveling expense was not what it is for airfare and lodging (without specimens cost) then I would be there in a heartbeat.

Always nice. X- pupa, or earlier.
Those damages happen to all of us. Raise them for weeks or longer, wait, then hope you can dispatch them, spread and get it into a case without
breaking something off. More than once I went from flawless to arrgh.
I just realized, I have a new set of calipers. Perhaps I'll try them on the male rutulus I have on the board, an X-ova which I let hatch indoors a weeks ago.

Would be great to have some pictures of the fair. If anyone here attends it.

Unfortunately, I've damaged the right forewing - Murphy's law.
The wingspan is exactly 100 mm in the dried specimen.

Forgive for the plug, but the link below is to an excellent podcast that I follow. The episode linked I think may be particularly relevant to the present discussion. These can be challenging cases for sufferer and diagnostician alike

I haven't seen it for at least a week or more. Perhaps it occurs at certain times of day or in certain areas where the internet is slower?

I have seen the message a few times in the past week.

wollastoni · by wollastoni » Mon May 13, 2024 1:02 pm

I have the feeling we don't face that issue since I've upgraded the forum version (on May 5th).
Did anyone face this Resource Limit error last week ?

The dark Florida specimens look very similar to E. philolaus, a Mexican species that strays into the Lower Rio Grande Valley of TX.

I suspect that they retain a dye added to the larval foodplant. Presumably these have never been seen in wild specimens.

The pink one is amazing! I never knew that form existed.

It has always been a strange phenomenon in my part of the U.K. that the spring brood of this butterfly which flies here in April & May is considerably less frequent that the summer brood flying from July onwards. The summer brood is probably the commonest late summer butterfly here but I only usually see a handful of the spring brood each year. Photos attached of a self caught pair of spring & summer broods. The spring brood is smaller & less heavily marked than the summer one here. Also a photo of a possible gynandramorph & a pink female example from my collection. I am still not completely sure how these pink forms are produced.

Texas & S. Florida). Does anybody know how closely (or distantly) the 2 species are related?

They are in different subfamilies - Aphrissa statira belongs to subfamily Coliadinae, whereas Pieris rapae of course belongs in Pierinae, so they are not very closely related.
