Sometimes things are so much fun you just can’t stop, and that is the way it is with Boisea rubrolineata at our house right now! You can go to the previous post to see obvious examples of B. rubrolineata and B. trivittata. One of the nice things about a home (or museum) insect collection is
you can ask questions that you may not have asked in field. The red corium veins of the specimens from Canyon County, ID this weekend were obvious. In the home collection, there were two specimens named as B. rubrolineata with subtle and faint red veins on the corium – one from Twin Falls County, ID and one from Morgan County, UT. A third specimen (sorry about the moth scales) from Morgan County, UT, shows only the faintest traces of red veins on the corium – even though this specimen was collected from the same rhopalid group as the previous Morgan County specimen. Are these specimens actually intergrades? Are these
species actually the same? Is the third specimen actually B. trivittata that I have mistakenly identified as B. rubrolineata because that is what it was associating with?
