I had the chance recently to visit Nevada on 5/1-5/2 and decided to take a shot at finding some Pseudocotalpa. Having never found this before I didn't really know what to look for all I knew was they liked really sandy habitats and fly around sunset for a short time. After doing a bit of research I found some dunes called Big Dunes that weren't too far from where I was staying so I headed out. I arrived around 6pm and loads of calosoma, tenebs, and blister beetles were out roaming the outskirts of the dunes. The beetle diversity dropped quite a bit once I actually got in the sandy dune section with eusattus muricatus being the main beetle. Right around 7:20pm I went out of the dune section since there was a lack of large creosotes which I heard they fly to and went to the gravelly outskirts and continued to look for Pseudocotalpa until 8pm. At this point I had all but given up thinking I wasn't going to find them and decided to just go to the dune section again and see if theres any weird inverts out in there. At around 8:30 I had gotten down into a "pit" within the dunes with a few small lying shrubs and stumbled upon four Pseudocotalpa crawling along the floor. The specific spot I found them in was fine sand without any creosote which shocked me but overall was quite a fun little trip.
