Mosaic Darners in mating position

Dear Sailortom,
We believe these are Mosaic Darners in the genus
Aeshna which is represented on BugGuide.  Several similar looking species are found in Idaho, and we do not feel confident providing a species identification.  Though you indicate they were “cruising marsh shore” they do not appear alive in your images.

Mosaic Darner

Thank’s. I am happy with the generic ID. The images are of living Darners. They perched on a dock long enough for pictures. Then they linked up, I assume to mate.

Your letter to the bugman:  Encountered this beauty on a sidewalk today. Wings appear hollow … is it just illusion?

Achemon Sphinx

Dear Chris,
This is an Achemon Sphinx, and you may read more about it on Sphingidae of the Americas.  The markings on the wings and the camera angle have created the illusion that the forewings are rolled, but they are actually quite flat.

Longicorn:  Neoclytus mucronatus

Dear Amanda,
This is a Longicorn or Longhorned Borer Beetle in the genus
Neoclytus, and it has no common name.  We believe we have correctly identified it as Neoclytus mucronatus thanks to this image on BugGuide.  It is one of the species that mimics a stinging wasp like a Paper Wasp for protection as the beetle does not sting, but potential predators are put off by the warning colors.

Longicorn: Neoclytus mucronatus

Thanks for the swift response! I’m glad you were able to ID this for me. The markings on the wing casings kept me from seeing that it was any kind of beetle. I guess mimicry works to fool amateur entomologists too.

Subject:  Large Orb – Albino?
Geographic location of the bug:  Boerne, Texas

Your letter to the bugman:  I have looked through MANY pictures of Orbs, but this critter seems unique. She seems to have the correct pattern for a black and yellow orb, but not the right colors. Can spiders be albino (besides the obvious cave dwellers), thoughts?

Pale Golden Orbweaver

Dear Adam,
We don’t know if this is considered a true albino, but we agree it is a Golden Orbweaver,
Argiope aurantiaBugGuide has an image of a similar looking individual that is called a “light color morph” and this BugGuide image is also of a light individual.

Daniel,
Thanks for the reply! Those do look similar, I am always d6o fascinated with the constant variety of nature. Have a great day
Respectfully,
Adam

Your letter to the bugman:  Have what appears to be a rare Histioea, but cannot identify it. These are seldom photographed from what I can tell. The observation is https://www.inaturalist.org/observations/19385404.

Diurnal Tiger Moth: Histioea paulina

Hi Trevor,
We have several diurnal Tiger Moths in our archives identified as
Histioea meldolae, including this individual from Colombia and this individual from Costa Rica.  We will forward your image to Arctiid expert Julian Donahue to see what he can provide in the way of an identification.

Julian Donahue responds.
Hi Daniel,
This is a perfect match for the female of the euchromiine Histioea paulina Walker, 1866, as figured in Seitz, described from São Paulo, Brazil–a long way from Ecuador, but I don’t have any information on the distribution of the species.
Nice moth!
Julian

Thanks Daniel and Julian for the id! I will update inaturalist with the info. Much appreciated and very exciting!!
