That is spectacular.

I wonder if this relatively common morph in your area is environmental or genetic? Perlman & Perlman demonstrated form fletcheri and others to be environmentally induced; Scriber wrote that such genetic changes are inheritable. I wonder if your "fletcheri" produce more fletcheri.

It is not a form of Papilio multicaudata multicaudata.

Adam.

Since you brought it up- the multicaudata I caught in southern Arizona look a lot more like grandiosus than ssp multicaudata. Anyone know what the story is on these?

The title says it all.
There is no way that there are as many legit sellers of, let's take the current examples of "stag beetles". I think that a person could make up an
insect, and someone would try and sell it. Better yet, how about asking for Meganeura livestock.

yes, morning is slow here, I have a series of rituals before the day really can get going, time to think.

Thanks for all the nice comments. I netted the real thing earlier this week in Colorado. It wasn't the grandiosus form but a nice female nonetheless. It was nectaring on thistle. Several others flew by, but not close enough to capture. Also got a Weidemeyer's Admiral (Limenitis weidemeyeri) in a wooded area (mostly Oaks).

Awesome. Thank you!

If it was under a rock near the river, it was almost certainly preparing to metamorphose into an adult. They seek out some protected spot on land to go through this phase.

It's what's known as a hellgramite, which is the larval form of a dobsonfly. The larvae are aquatic, while adult dobsonflies are winged -

In New York, the local species of dobsonfly is Corydalus cornutus -

Found this guy under a rock next to the Delaware river in New York State. It was about 3 inches in diameter after it balled up so it was big!
The iNat and Seek apps have no idea. Says it may be some sort of arthropod. I'm scouring my insect books...nothing.
Please help! I need to know what it is! It was so cool.

Hello Everyone... Happy early Summer!

This year, the lilacs really put on an impressive show in late May - early June. I spent a week (4-6 hrs. each afternoon) sitting in a lawn chair with my newly acquired close focus binoculars & naturally, of course, haha, my net. As an aside, I would highly recommend these binoculars, Pentax - "Papilio II" - 6.5X x 21... they are small, light weight, have a crystal clear image & can focus down to only 18"... & were, to boot, very reasonably sale priced... around $125.00 CAD @ Amazon. I continually scanned the lilac blossoms every day & was finally rewarded, late on 30th May, @ 6:00 pm, with the collection of a stunning aberration of our common Canadian Tiger Swallowtail, Papilio canadensis pictured below

In the distant past I've had the good fortune to collect 2 other interesting abs. of P. canadensis... ab. "fletcheri" which is familiar to long time members/viewers of insectnet.com & the unusual ab. pictured in my avatar... ab. "radianthus"?

The next day, 1st of June, on the same lilac bushes, I collected a perfect, freshly emerged, male Black Swallowtail (P. polyxenes asterius)... only the 3rd ever collected in my area. I can post photos later, if wanted, of this latest P. canadensis ab., as it is still on the spreading board ... I leave all my lepidoptera specimens on the boards for a month, minimum, to ensure complete dry down with no drooping.

Delias are unpalatable too. That's why they are at the heart of several mimicry rings in SE Asia and New Guinea.

livingplanet3 wrote: Sun Jun 22, 2025 8:43 pm Very nice! Certainly, this must be among the most impressive of the larger pierids. Of note in this species, is that its wings contain glacontryphan-M, a potent peptide toxin, which is also a component of the venom of cone snails (Conus spp.). Cone snails use this peptide (delivered via a stab from a harpoon-like, specialized radular tooth) to paralyze their prey, but in the case of Hebomoia, it must somehow function as a deterrent against predators.

Thanks for enlightening me. Fascinating. I had no idea that Hebomoia gained protection in this way.

Here's a 2012 paper on the subject -

Impressive specimen John !

There are more flags, but sometimes I wonder if posting them is undermining our efforts. The simplest thing is that the scammers are usually out of their element. I do want to clear up a comment I made about using peat moss- spaghnum is the moss I like using for a substrate.
I also have to admit I have been tricked, and it was from not following my own advice, and there are different kinds of "scammers", for some, apparently it's a job, for others, they just can't follow through, good intentions don't make a road.

These lopsided wings occur in different butterfly families as well; the following specimen was a very poor/awkward flier which first drew my attention to it...

Yes, those are Argema mimosa cocoons depicted.
In America, we also write dates differently, we write 06/20/25, not 20/06/25
While you may ship them in the USA, it is illegal since they are non natives
They spelled the species incorrectly
Member just joined, along with the apparent legit buyer
These "possible?" more like probable scammers should hook up with the ones selling Stag betels

While warnings about and praise for sellers are appropiate in the classified ads, there are a lot of experienced individuals here using this site, I cannot be scammed, and neither can most of the other users here.
I have seen a number of new persons using the classifieds, it's nice to see, but I know who is legit, and who is not just from reading your ad most of the time.

Ok. one more thing. Those Actias dubernardi cocoons in the classified ad? They look familar. maybe they aren't mine, but a few years ago, I raised a batch of a lot of the moth and sold most in bulk. I used peat moss in boxes and the larva spun those whitish nearly perfect orbs. Anyway, that's how to make a egg shaped dubernardi cocoon.

While not as experienced as you, I am learning very quickly and saw all the massive red flags. No price in the main ad. No shipping info. Suspiciously familiar picture, I swear I've seen it in the past. A vastly different second picture with a non-American dating structure. If you look at the picture zoomed in, the date appears to be spliced in.

Thank you for your vigilance, I have deleted his accounts.
