I have become fascinated with Cuckoo Bees (Nomadidae sp). Not only are Cuckoo Bees visually appealing, but they exhibit really interesting behavior. And, as a whole, they are also hard to identify down to the species level without intense scrutiny, even for the experts, which I kind of like (on slightly pathetic note) since I still have so much catching up to do regarding my own bee identification skills.
