Reaumur calls them Lions des pucerons (plant-lice lions), because 

 their larvae, which resemble the larvae of the Ant-lions, and which 

 live on plants, feed on plant- 

 lice. They attack also cater- 

 pillars. Their mandibles are 

 provided with a canal for suc- 

 tion, like those of the foregoing 

 species.

Osmylus (Fig. 408) are rather rare ; but may be found in the 

 month of August in the shrubs which border ponds. They also 

 belong to the HemerobidcB. Their larvae live in wet ground.
