- Fireflies get mimicked a whole lot
- It's super tricky to separate some of the mimics from actual fireflies, especially when you get into the soldier beetles (family Cantharidae).
Unless you were to get on this click beetle's level, you would think it's a firefly. I'm quite pleased with this picture, though it could use a little more touching up later. Denticollis denticornis is this beetle's name, and it was making its way across a moss and lichen-covered log, providing a great background.
This is the only species in its genus in North America, and its mimicry of fireflies is a predator defense. I haven't found any information about whether or not the beetle itself is toxic, or if it's just getting a free ride thanks to the fireflies. A predator would see it and be all "I'm staying away from that beetle, it must be toxic!" and D. denticollis would chuckle to itself and walk away.
