- Hemiptera, Coreidae
- Size
- 15-20 mm (0.6-0.8 inches)
Natural Habitat
Found on various plants, especially conifers (for Leptoglossus occidentalis) or cucurbits (for Anasa tristis). Often seen near human dwellings, looking for overwintering sites.
Diet & Feeding
Primarily plant sap. Leptoglossus occidentalis feeds on the developing seeds and cones of conifers. Anasa tristis feeds on the sap of cucurbit plants.
Behavior Patterns
They are typically slow-moving. When disturbed, they may fly away or emit a foul-smelling liquid as a defense mechanism. They often seek shelter indoors during colder months.
Risks & Benefits
Potential risks include being a minor pest to conifer trees (L. occidentalis) or a significant pest to cucurbit crops like squash and pumpkins (A. tristis). They do not bite or sting humans and are generally harmless, though their defensive odor can be unpleasant.
