I found this guy on a dry rock in a small stream in the far northern Sierra Nevada mountain range. One of my friends said it looked like a “cross between a bee and a long horned beetle.” then he quipped that was not possible. I was surprised as he is hard to stump!

Lion Beetle

Dear S. Dykstra,
When we first received some excellent images of a Lion Beetle,
Ulochaetes leoninus, in 2009, we were quite confused and amazed ourselves.  BugGuide now has many more images of this unusual Cerambycid, but there is still no information posted on the Info page.  According to the Introduction to California Beetles by Arthur V. Evans & James N. Hogue:  “The Lion Beetle … looks and behaves just like a bumblebee, even attempting to sting with its ovipositor.  When disturbed, the Lion Beetle raises its abdomen forward over its back while flapping its wings, reinforcing its bee-like appearance.”

Location: Northern Sierra Nevada, California
