Economic Importance:

Limited.

Known host plants: 

Derbidae are known or assumed to feed on fungal hyphae as immatures.  The significance of adult host associations are unclear.

none reported.

Hosts from Wilson et al. 1994; plant names from USDA PLANTS or Tropicos.

Recognition:

Pale, fragile forms; wings greatly exceeding the abdomen; frons extremely compressed, head strongly projecting; pustules along claval vein; clavus open, antennae lacking appendages; in lateral view, head projecting in front of eyes for a distance subequal to width of eyes (similar to Anotia); costal margin expanded to a free appendage half as wide as wing at that point
