~80 spp. in 9 genera of 4 subfamilies in our area(1)
, ~500 spp. in 66 genera of 11 subfamilies worldwide(1)(2)
(our spp. to ~30 mm?); neotropical Gauromydas heros
is world's largest dipteran(1)
Large flies, often wasp mimics. Have prominent, clubbed antennae and distinctive wing venation:
Artigas & Papavero (1990) contains a key to the genera of Mydidae in the Americas
. Note that the majority of genera treated in Artigas & Papavero are restricted to meso- and South America and thus do not occur in our area...but those that do are listed in the "Numbers" section above.
Worldwide, primarily in tropical and subtropical regions (most diverse in Subsaharan, esp. so. Africa but poorly represented in the Oriental Region), with some representation in temperate climes(1)
; in our area, most spp. have restricted distribution, mostly in sw. US(3)
. Mydas clavatus
is widespread, largely eastern.
Primarily in arid environments, although quite a few species occur in forests(1)
, e.g., Mydas clavatus
Life cycle details not known for many groups; generally, larvae live in decaying wood or soil; some known to prey on beetle larvae(3)
Larva and pupa of Mydas clavatus:
of large spider wasps (Pompilidae: Pepsis
) by Mydas flies is discussed in(4)
- Robber Flies (Mydas flies have prominent clubbed antennae, different wing venation).
