 Family BIBIONIDAE 



These are flies of moderate size, with bodies clothed with long hairs; legs long and stout; 

 antennae short; stout, many-jointed. They appear very early in spring and in the U. S. are 

 termed "March flies," but this name would not apply in our Province. The larvae feed on 

 roots of grasses and some on decaying vegetable matter. They have ten pairs of spiracles.

Family SIMULIDAE 



The "Black-flies" — like the mosquitoes — are only too well-known in our woods in early 

 summer. The larvae live in great number in running streams, sometimes forming a coating 

 like moss on the rocks. The cocoon in which the pupa stage is passed is fastened to the rocks.
