A male Ectemnius cavifrons [1,2] on the beehotel.
This year these bees were frequent visitors on the beehotel when the day started to near its end. They use the beehotel for sleeping. Finding a fitting sleeping spot turned out not to be an easy task as they spent a substantial amount of time inspecting all available cells accross all nesting blocks before finally crawling in one for the night.
