"Proboscis case" in Sphingidae pupae (continuation)
by lamprima2 » Sun May 26, 2024 4:09 am
structure and function of Sphinginae pupae's maxillary loops (aka "jug handle”). There was no reply. I contacted a few specialists in this area. One of them replied: "If you would look inside, you will see that the galeae extend from the head into the loop, then the galeae bend sharply back and turn back to the head of the pupae. On the pupae, you can see the distal part of the developing galeae in the midline of the pupae between the developing wings." I spent some time trying to find something illustrating this observation and finally found this amazing photograph by M. Albrecht (from Danner et al., “Die Schwarmer der westlichen Palearktis,” Herbipoliana, Band 4/2, 1998, Plate 46).

I only saw males and despite lilacs in full bloom I wasn’t able to spot a female. I’m still missing a female of this species leaving in Canada for over 3 decades. I suppose I did not make enough effort.

Toronto And Mississauga: they are flying here around first two weeks of June, one generation only. They are larger than Canadensis and somehow looks like hybrid between glaucus and canadensis.
West of Toronto ( Hamilton, Cambridge and south west of it) I never recall to see tigers there in the spring but I maybe missed them. They are flying starting in end of July, August. I assume these are true P.glaucus as they certainly look like.
North/ east of Toronto ( about 100km ) we can easly find true canadensis around last two weeks of May, begin of June. They are much smaller.
I also found once at Georgian bay Tiger in mid July which I thought was canadensis but it was too late in the season and it is also larger specimen.
It is complex group and to exactly specify fly times and which actually species flies when and where one has to spend more time like Chuck is trying to do now in his region.

Well, it is not as simple as I thought it is too.
GTA is rather large and looks like it is boundary zone for Tigers. I don’t have time to post my observations but I’ll do it at some point

Note that the worker ants are wingless.
Interestingly the larvae of some Lycaenid butterflies live in these nests, mimicking ant larvae.

Re: Buying specimens in bulk for an entomology workshop

Dear Chuck,Chuck wrote: ↑Fri May 10, 2024 11:55 am I have a bin of various dried US leps you can have. They are of course papered and dried, so would require softening in order to be spread.
I'm amazed I even have any. I always kept many extras around for projects such as this, but it's been a long time since anyone had asked me so I unloaded thousands last year to an institution.
So I can send 100 or more if you want. But why not have the kids catch then set fresh specimens? It will be easier to set them, and the specimens would be theirs.
Which tribe/ nation are you working with?
Thank you so much! Can you please PM me your price? Getting parental/school permits to collect butterflies is a lot more work for the university (University of Montana) and handling 50-60 kids would be difficult in the field. I will be relaxing the specimens 48 hours in advance and then get them to pin. I will be working with the Flathead reservation tribe school students. They will be taking the specimens with themselves. We will have half a day of butterfly walk (no catching in the wild, but I will be catching a few to show them some interesting biology), followed by DNA extraction of a few Pieris butterflies that we have reared in the lab and pinning. I unable to send you a PM.

I am curious as to what species this is.
I've tried Google as well as Google Lens. Both continually and completely ignore the wings.
I've also tried searching based on the head, thinking that perhaps the mandibles are a distinguishing feature.
This is the second one I found. It was early morning (relatively) and still cool (relatively), so I am assuming it was waiting for the sun to hit its spot, it seemed very languid.
Location is south of Thailand, rural environment.
I am ready to be educated
Thank you!

I’ve seen about 100 P.canadensis two days ago 150km north of Toronto, they were all fresh and many came to mud puddling (Urine bait).

So I headed a bit south where there are two ponds with shores, and watercourses, etc. Saw two. Drove 20 minutes south into the Bristol Hills, and saw nothing. Saw one on the way, one on return, both at valley level.
