Synonyms and other taxonomic changes
Genera treated in the Opetiinae in(1) now belong to 2 diff. subfamilies, Melanderomyiinae and Microsaniinae; the Palaearctic genus Opetia is now considered to be a sole member of Opetiidae, thus there is no subfamily Opetiinae in Platypezidae
Explanation of Names
Platypezidae Latreille 1829
4 subfamilies, with ~70 spp. in 17 genera in our area(2) and ~280 spp. in ~30 genera total(3)
Mostly 2-5 mm (Calotarsa 6-10 mm)
Mostly n. hemisphere, incl. much of NA
Late summer-fall
Adults may feed on fungi. Some groups take honeydew from leaves(4)
Males sometimes swarm, and females are attracted to these swarms. Some are attracted to smoke. Larvae live on fungi, some genera are associated with stinkhorn mushrooms. The elongated tarsi may be an adaptation for spreading host spores.
