Xyela Explained

Xyela is a genus of sawflies, belonging to the family Xyelidae.^[1]

The genus was described in 1819 by Dalman.

Ecology

The genus has cosmopolitan distribution.^[2]

Larvae of most species of Xyela live and feed in the developing staminate cones of Pinus (Pine) species. One species, gallicaulis, forms shoot galls. Adults fly early in the spring and are commonly found in large numbers on the catkins of Salix (Willow) or Alnus (Alder) trees near their host plants.^[3]
