Large flying insects at night
Many of the large flying insects you see at night are nocturnal species attracted to artificial light, especially around lamps, windows, and porches. The most common groups include moths, beetles, crane flies, and sometimes predatory insects like mantises. Research shows that artificial light disrupts their natural navigation, causing them to circle lamps or gather around them.
Moths
- The most common large nocturnal flyers.
- Sizes range from small to very large (e.g., sphinx moths).
- Often fuzzy, with wide wings and erratic flight.
- Attracted strongly to artificial lights.
Beetles
- Cockchafers / May beetles (Hannetons) – big, brown, noisy flyers.
- Longhorn beetles – elongated bodies, long antennae.
- Ground beetles – some species fly toward lights.
Crane Flies
- Very long legs, slender body.
- Often mistaken for giant mosquitoes (but harmless).
- Clumsy flight, often bumping into walls.
Katydids & Bush Crickets
- Green or brown, leaf-like bodies.
- Large hind legs, long antennae.
- Attracted to lights occasionally.
Lacewings
- Delicate, transparent wings.
- Medium to large size.
- Often green or brown.
Large Mosquitoes & Midges
- Some species are active at night.
- Usually smaller than moths or beetles, but can appear large when flying close to lights.
Praying Mantises
- Not common, but sometimes attracted to lights while hunting other insects.
- Large, slow, hovering flight.
