8 Farmers’ Bulletin 1259. 
The adults (fig. 8) are rather robust, four-winged insects. The 
male is black with reddish yellow legs and has beautiful feathery 
feelers, or antenne. The female has the head and first two thoracic 
segments reddish brown and the third thoracic segment and abdomen 
black. Her feelers are rather slender and not feathery. 
Fic. 8.—Leconte’s sawfly : A, Adult female; B, adult male. About eight times natural size. 
The sawflies get their name from the complicated egg-laying organ 
of the female. It is well named “the saw,” having blades and teeth 
and being used exactly as a saw when tearing into the leaves in cut- 
ting a pocket for the eggs.
