Sexton Rove Beetle
A broad, somewhat flattened rove beetle found in the nests of social wasps and in tree hollows containing decaying insect remains. Its expanded body shape is adapted for life in cavity habitats.
Did You Know?
This beetle waits for wasp colonies to die in autumn, then enters the abandoned nest to feast on the remaining dead wasps and their brood.
Klamath Weed Beetle
A dark bronze to coppery-brown beetle with a convex, heavily punctured body. It was introduced to control the invasive Klamath weed (St. John's wort) and became a classic biocontrol success story.
Did You Know?
Its introduction to California in the 1940s reduced Klamath weed infestations by over 99%, saving millions of acres of rangeland.
