False Potato Beetle
Leptinotarsa junctaAlso known as Horse Nettle Beetle
False potato beetles closely resemble their notorious agricultural cousins, featuring distinct black and pale yellow stripes along their rounded wing covers. They specialize almost exclusively on wild nightshades like horse nettle rather than commercial potato crops. When threatened, adults feign death by tucking in their legs and dropping straight from leaves into the dense undergrowth below.

Responsible observation
- Inspect Host Plants: Scan horse nettle foliage in sunlit fields where adults and reddish larvae gather to feed.
- Check Elytral Stripes: Distinguish it from look-alikes by looking for a brown space between the middle dark stripes.
- Approach Gently: Move slowly to prevent adults from dropping off leaves to hide in the soil.
