Larvae of this species were found November 24, 1910 in partly 

 decayed chestnut bark at Nassau, N. Y. There were also many 

 similar appearing, though 'very different larvae, Medeterus, which 

 apparently preyed upon these midge larvae and became relatively 

 more abundant in the spring. Adult midges were reared from April 

 26th to the last of May or in early June. The insect is evidently 

 allied to W. calciequina Felt, from which it is most easily 

 separated by the stouter antennal segments, color differences and 

 the longer, stouter terminal clasp segment. Larvae collected in 

 the field April nth remained alive and under constant observation 

 till May 15th, the fly being foimd June 5th. The larvae show no 

 sign of a breastbone in the fall and early spring.
