Ah, I didn't even think of the temp issues because they are supposed to be inert so the metals of whatever coin you have do not oxidize or "tone" in any way. However the same plastic may very well be toxic to organic life at higher temperatures. I'll need to research that more I suppose.Hey Vfox, I appreciate the idea, and they are cheap. Unfortunately, the plastic used in them is extremely toxic to life forms. They off gas hormone mimickers and benzenes (? something like that ?), when hot. Seeing as I will be in 100*+ temperatures, I will not use those plastics for collecting. Otherwise I would have already ordered them!
I am going to collect scorpions in the U.S. I am still planning on going to Mexico, but only to take pictures! I don't know which will come first. It depends on how things go until it warms up. But I will not be collecting scorpions in MX, unfortunately their laws are very strict, and I don't want to go to prison. But I hope to get some cool pictures!
Yeah, don't do anything to get stuck in a Mexican prison, especially southern Mexico...it'd be best to avoid lol. I would imagine collecting out west is still viable for another month or so until the desert winter really sets in. Have you ever collected this late in the year? Like in a post I made yesterday I just found a small culture of Parcoblatta pennsylvanica cockroaches in 54 degree F temps here in PA; according to the literature I could find they are supposed to be dormant until spring.
Obviously the books underestimate the active cycles of most inverts. I've seen insects (not during warm spells but regular cold temps) and other inverts fairly active around here until the first snow falls around mid to late December. Most bees have already vanished but some, like yelowjackets, are still very active around here...along with stick insects and stink bugs...flies of all sorts...carpenter ants...loads of spider species...etc etc.
