Stenochironomus pulchripennis
(Coquillett, 1902)
Stenochironomus pulchripennis is a of non-biting midge in the Chironomidae, first described by Coquillett in 1902. The Stenochironomus is characterized by reduced wing venation and includes species often associated with decaying wood and aquatic . Like other chironomids, do not feed and rely on larval energy reserves.

Identification
Members of Stenochironomus can be distinguished from other by reduced wing venation, particularly the absence or reduction of the anal . Specific identification of S. pulchripennis requires examination of male genitalia and antennal structure. The specific epithet "pulchripennis" ("beautiful wing") suggests distinctive wing patterning or coloration.
Habitat
Larvae of Stenochironomus are typically found in decaying wood in aquatic or semi-aquatic environments, including submerged logs and woody debris in streams, ponds, and wetlands.
Distribution
North America. The was described from the United States, and iNaturalist observations suggest occurrence across eastern and central regions of the continent.
Diet
Larvae feed on decaying wood and associated microorganisms. do not feed.
Life Cycle
Complete with , larva, pupa, and stages. Larval development occurs within decaying wood substrates.
Ecological Role
Larvae contribute to decomposition of submerged wood in freshwater , facilitating nutrient cycling and serving as prey for aquatic and fish.
Human Relevance
No direct economic or medical importance. Occasionally collected in freshwater biomonitoring studies as indicators of quality.

Taxonomic note
The Stenochironomus was historically considered a subgenus of Chironomus but is now recognized as distinct based on larval and wing venation.
