Alycaulini

Alycaulini species are distinguished from other gall midge tribes primarily by larval and adult morphological characters, including features of the antennae, wing venation, and larval mouthparts. Definitive identification requires examination of genitalic structures and is typically performed by specialists in Cecidomyiidae taxonomy.

Habitats are determined by host plant associations; members occur wherever their host plants grow.

Worldwide distribution corresponding to the ranges of host plant species.

Life cycle follows the typical gall midge pattern: eggs are deposited on host plant tissue, larvae induce gall formation and feed within plant tissue, pupation occurs either within the gall or in soil, and adults are short-lived. Specific details vary by species and host plant.

Larvae act as gall inducers, causing abnormal plant growth that provides shelter and food. This interaction represents a specialized form of plant-herbivore relationship.

Most species have minimal direct economic impact. Some may affect ornamental or crop plants through gall formation, though specific pest status of individual species is poorly documented.
