status

 

Subfamily Leptogastrinae  

Females in the genus Leptogaster   drop, singly, 1 to 8 eggs to the ground as they are flying or resting on vegetation. The oval eggs are amber to light yellow-brown or light yellow. They range in length from 0.32 to 0.50 mm and width from 0.25 to 0.39 mm.

The surface of the eggs of Leptogaster   and Psilonyx   is either smooth, or they have varying shapes of polygons without ridges. The eggs of Beameromyia   and Tipulogaster   are smooth without ridges. Aeropyles have not been observed on Leptogastrinae   eggs. There are one or two micropyles in a smooth to elevated area. The egg stage lasts for 9 to 14 days.

Leptogaster   larvae develop in soil; those of Mesoleptogaster   are said to develop in deciduous trees. Morphological information, including figures, is available for Leptogaster   larvae and pupae, and Apachekolos   pupal cases.
