Atrichopogon levis

(Coquillett, 1901)

grass punky

Atrichopogon levis, commonly known as the grass punky, is a biting midge in the Ceratopogonidae. Larvae develop within grass stems, particularly bluegrass (Poa pratensis), feeding on plant juices. females are aggressive blood-feeders on mammals, including humans, causing irritating bites. The complete from to adult takes approximately 3–4 weeks under favorable conditions. The is a significant nuisance pest in grassy areas and has been recorded from Hawaii.

Host Associations

  • Poa pratensis - LARVAL_HOSTBluegrass; primary larval development site
  • mammals - ADULT_HOSTincluding humans; blood source for females

Life Cycle

Complete from to takes approximately 3–4 weeks under favorable conditions. Eggs are laid in grass stems. Larvae bore into and develop within grass stems, feeding on plant juices. occurs within the grass stem. Adults emerge from pupal cases in grass.

Behavior

are strong fliers. Females are aggressive biters, attacking humans and other mammals for blood meals. Larvae bore into grass stems to feed and develop.

Ecological Role

Larval stage acts as a plant within grass stems. females function as a nuisance pest and potential through blood-feeding on mammals.

Human Relevance

Significant nuisance pest due to aggressive biting of females. Bites are irritating to humans. Used as a source of insects for laboratory studies.
