Non-biting Midge

Natural Habitat

Found globally near freshwater sources like lakes, ponds, and streams; adults are often attracted to artificial lights and reflective surfaces like windows.

Diet & Feeding

Adults usually do not feed at all or consume only nectar and honeydew; larvae (known as bloodworms) feed on organic debris and algae in water.

Behavior Patterns

Adults form large mating swarms in the evening. They have a short lifespan of only a few days focused on reproduction. They are frequently confused with mosquitoes but do not have a biting proboscis.

Risks & Benefits

Benefits: Larvae are a vital food source for fish and birds and help cycle nutrients in water bodies. Risks: While they do not bite or transmit disease, large swarms can be a nuisance and may occasionally cause respiratory allergies in sensitive individuals.
