Hello to another Louisianian~!
I live in Shreveport, the the northern part of Louisiana!
Well, I'm into the coleoptera(mainly, Lucanidae & Scarabeidae), however, I could not collect any specific species that I always wanted to. I saw Lucanus capreolus, Lucanus placidus, Phileurus valgus, Cyclocephala lurida(I think), Euetheola humilis in my area until now.
I have been collecting the Cyclocephala lurida by using blacklight at my backyard. Since they eat grass to grow up. I could easily collecting them by putting my blacklight and white curtain on the grass. For some reason, I could not collect the Euethola humilis with same method, however I collected while I was at the street light. E. humilis are attract to the lights on whenever the sun goes down, and it is dark. That might be the best explanation of the time when they come out. You need forceps(if you want) and flash light. If you are planning to collect a lot of them, might need some containers. Several years ago, I was able to collect around hundreds of E. humilis, but now my area is in a lot of construction and I cannot see much. This year, I have collected around three to four dead, and one or two alive ones.
I collected L. capreolus, L. placidus, and P. valgus like three to four years ago, and haven't seen for a long time...
Did you had Trypoxylus dichotomus when you were in Japan? or right now in America?
I have been breeding them while I was in South Korea, but could not find the breeders in America...
