Identification

are small acalyptrate flies. Identification to and level requires specialized keys; Cogan (1975) provides keys to Afrotropical genera and species, while Prado (1973) offers keys to world genera. The is distinguished from related acalyptrate families by combinations of chaetotaxy, wing venation, and genitalic characters, though specific diagnostic features vary among genera.

Habitat

Larvae inhabit tunnels in dead wood, specifically those created by wood-boring beetles, , and other flies. are found in association with these larval .

Distribution

Representatives occur in all major biogeographic realms: Palaearctic, Nearctic, Neotropical, Afrotropical, Oriental, and Australasian/Oceanian. Distribution records include Denmark, Norway, and Sweden.

Diet

Larvae function as scavengers or of larvae within wood-boring tunnels. The specific dietary habits of remain undocumented.

Host Associations

  • wood-boring Coleoptera - larval and food sourcelarvae occupy tunnels of wood-boring larvae
  • wood-boring Lepidoptera - larval and food sourcelarvae occupy tunnels of wood-boring larvae
  • wood-boring Diptera - larval and food sourcelarvae occupy tunnels of other wood-boring fly larvae
  • Pseudococcus comstocki - Turanodinia coccidarum reared from masses of this mealybug

Life Cycle

Larval development occurs within tunnels of wood-boring insects. The of at least one Afrodinia has been described. Complete details remain unknown for most species.

Behavior

Larvae have been observed to have or scavenging relationships with xylophilous insects. Possible has been suggested for Odinia foliata larvae, though this requires confirmation.

Ecological Role

Larvae act as entomophages of xylophilous insects in dead wood, potentially regulating of wood-boring beetles, , and other flies. Their role as versus scavengers remains partially unresolved.
