Desmocerus palliatus Emmitsburg, Frederick County, Maryland, USA June 23, 1985 Size: 25 mm
It seems that everyone knows this beetle. I think it was even on a postage stamp at one point. I guess that bugguide doesn't really need another image but I'm posting this to discuss preservation techniques for the collectors out there. Unfortunately in pinned specimens, the brilliant orange band eventually fades to a greasy yellowish gray color. However you can salvage things (sometimes...doesn't always work!) by soaking the specimen in xylene for a few days. I have also tried acetone, gasoline, soapy water, toluene, and even ether but xylene seems to work best (good for rescuing greasy tiger beetles too). You still loose the orange but at least you get a nice bright yellow band and a beetle that remains quite beautiful. This beetle is over 20 years old and it still looks great. These beetles are very common on elderberry bushes behind our house in Belgrade, Maine. They come out like clock work on the 4th of July weekend. Kind of like natural fireworks!
