Assassin Bugs: Beneficial but Painful—Identification & Caution

Identification

• Wide range: Americas, Europe, Africa, Asia.
• Ambush hunters: inject toxin that liquefies prey.
• Eggs: clusters in cracks, under rocks.
• Nymphs: <½ in., orange/black striped, translucent.
• Adults: up to 1 in., cone head, curved beak, long antennae/legs, beige with black marks, folded wings.

Hatching & Development

• Eggs hatch soon after laying.
• Nymphs take 1 year to mature (overwinter in bark/logs, molt in spring, adult by June).
• 1 generation/year. Wingless nymphs molt 4–7 times.

In the Garden

Prey liquefied and sucked dry. Bite painful—sharp, intense. Most get red bump + itching. Allergic reactions: worse swelling/pain for days. Recognize them to avoid accidental contact while they control pests.
