Wheel Bug (Nymph)
Arilus cristatus
- Order & Family
- Order: Hemiptera, Family: Reduviidae
- Size
- Nymphs start very small; adults can reach up to 1.5 inches (38 mm).
Natural Habitat
Found throughout North America in gardens, orchards, deciduous forests, and fields vegetated with shrubs and trees.
Diet & Feeding
Strictly carnivorous; they are generalist predators that eat caterpillars, beetles, bees, and other insects using a piercing-sucking proboscis.
Behavior Patterns
Solitary predators that ambush or slowly stalk prey. They undergo incomplete metamorphosis, with nymphs like this one molting several times before developing the characteristic dorsal wheel or cog.
Risks & Benefits
Extremely beneficial for natural pest control in gardens. However, they can deliver a very painful bite if handled or provoked; while not medically significant, the pain is described as worse than a bee sting.
