Re: Colorful Rare Orthopterans

Not exactly "beautiful"... certainly more like "totally bizarre" Orthopterans offered for sale in the past.

Schizudactylus monstrosus - Pakistan (truly an appropriate scientific name!)

This is Amblycheila hoversoni, the largest tiger beetle in N. America. Native to south central TX.

Right up front they state they couldn't do a more comprehensive analysis due to lack of samples (specimens).

It would be interesting to know what other Nymphalid Speyeria and Argynnis are closest to; Euphydras maybe?
Interestingly Speyeria is treated as Argynnis by some websites. They are in Heliconinae subfamily so the closest would be Boloria as it is in the same Argynni tribe and then would be Heliconius and other.
Euphydras is in subfamily Nymphalinae

Chuck asked an interesting question. I expect that there must have been, since it seems the species has been moved back to Argynnis and would appreciate hearing about them from someone who knows.

Dave,

It seems you are right, and apologise for the error. I note that books used that name, however I have just seen that
http://yutaka.it-n.jp/hel/710080001.html
treats it as Argynnis childreni childreni Gray, 1831

As a result I will change the name back in the subject line after posting this.

Adam.

Ag Drones

by 58chevy » Wed Mar 22, 2023 4:29 pm

This might be of interest to entomologists & collectors, since agricultural spraying affects insect populations. For better or worse, it looks like the drones are here to stay.

Another cool genus is Amblycheila from the western U.S. and northern Mexico. I've only had the opportunity to catch A. cylindriformis on the Great Plains.

With Fritillaries spread across the northern hemisphere, has there every been a study to determine where they developed and how they spread across the continents?

Homerus Swallowtail Life Cycle

An interesting 3 yr. old video depicting the complete life cycle of this magnificent butterfly:



Another 4 yr. old video on a Homerus Genetics project; both videos are by the same researchers:

Fabulous! One of the most eye-catching fritillaries I've seen.

Argynnis childreni

by daveuk » Tue Mar 21, 2023 10:21 pm

Back in the day (late 1970's, early 1980's) this used to be a readily available species for collectors at least here in the U.K. with most (if not all) specimens coming from India. It was one of the first tropical species I owned
I have an Indian pair in my collection which is over one hundred years old. No pictures of that pair currently. They are still in reasonable condition.
Common names are Himalayan Fritillary/ Large Silver Stripe.
This pair shown upper & underside are from
Viet-Nam

Thank you eurytides for that explanation.
I never really gave it much thought; I only noticed
that some males were "somewhat" diffrent looking
than the greater number that I have encountered.

ChatGTP not so bright

by Chuck » Tue Mar 21, 2023 8:49 pm

Finally got into ChatGTP AI. I asked it to differentiate between ssp of Ornithoptera victoriae. Among the ssp it gave me was aesacus and hauseni, as well as victoriae and regis. It did not cite other ssp.

I asked it a different question, a tough question, and it totally failed.

The nanoscale structures on the scales will have some variation, just like everything else. If the structures are off by a few 10s of nanometers, you will see a slightly different color (caused by interference of light rather than reflection or absorption).

Those are pretty awesome (natural) abbs. that you have managed John. I've never seen anything like them naturally occurring.

Mighty special finds indeed....🎉😱☺️
