Because I have been remiss at blogging about beetles recently, today I’ll post two Beetles of the Week. Both are members of the carabid tribe Lachnophorini. The first is a member of the genus Calybe, which are elegant, ant-like species that live on sand or silt shores of bodies of water (rivers, lakes). I found the Calybe sallei, below, in Texas.
The second is Lachnophorus elegantulus, a common species on gravel river shores in the Southwestern USA and neighboring Mexico.
Why do they have so many very visible.. hairs..? (I can’t remember the proper name)
They are called “setae”. I’m not sure why the have so many – perhaps it makes the sharp boundaries of their bodies a bit harder to see for predators.
