Pigweed Flea Beetle
Disonycha glabrataAlso known as Striped Pigweed Flea Beetle
Pigweed flea beetles are striking leaf beetles recognizable by their bold black and cream longitudinal stripes and a bright orange pronotum. Both adults and larvae feed voraciously on amaranths, chewing characteristic small holes through the foliage. When startled, adults use powerful, enlarged hind legs to spring away in an instant.

- Check Leaf Undersides: Inspect under leaves to discover yellow egg clusters or small larvae.
