Colorado Three-lined Leaf Beetle

A small, elongated beetle with an orange-yellow body and three dark longitudinal stripes on the elytra. It feeds on tomatillo and ground cherry in the western United States.

💡

Did You Know?

Like other Lema species, the larvae cover themselves in their own frass, which may serve both as camouflage and as a deterrent to parasitoids.

Lesser Swallow Prominent Moth

A white moth very similar to the Swallow Prominent but with a thinner dark wedge mark and a clear white hindwing. It is associated with birch rather than poplar.

💡

Did You Know?

It can be reliably separated from its close relative only by examining the width of the forewing wedge mark.
