placed on top of whole springtails.” 
Genus Trichoscapa Emery 
Trichoscapa membranifera Emery 
Wilson, 1953 : “Details of larval feeding seem to be sim- 
ilar to those in the case of Strumigenys. In addition, the 
Trichoscapa were never observed to participate in any 
sort of trophallaxis, either between workers or between 
workers and larvae” (p. 484). The life cycle was found to 
be: egg, 13 days; larva, 19 days; pupa, 19 days (p. 491).
