Florida Predatory Stink Bug

Euthyrhynchus floridanus

Florida predatory stink bugs use a sharp, piercing rostrum to inject paralyzing saliva into caterpillars, beetles, and other crop pests before drinking their fluids. Newly hatched red-and-black nymphs often hunt cooperatively in small packs, allowing them to subdue prey much larger than a single nymph. Females lay clusters of barrel-shaped eggs on leaves, and adults display metallic blue-black and orange-red warning colors backed by defensive scent glands.

Safe to observe at a normal distance; may release a mild foul odor if handled.
Responsible observation
  • Look on foliage: Search sunny garden plants, citrus trees, and shrubs where caterpillars gather.
  • Spot the nymphs: Bright red and black young bugs often hunt together in groups on leaves.
  • Avoid handling: Disturbing the bug triggers its scent glands, leaving a pungent odor on skin.
