Insects Reared from Goldenrod Galls Caused by Eurosta solidaginis Fitch (Diptera: Trypetidae) in Southern Ontario

Studies of the goldenrod gall caused by Eurosta solidaginis Fitch have been made by various authors who reared insects from the galls in North America, e.g. Hughes (1934), Milne (1940) and Ping (1915). Snyder (1898) described the emergence of an adult fly from a gall in Illinois. In Canada, insects...

Description
Summary:Studies of the goldenrod gall caused by Eurosta solidaginis Fitch have been made by various authors who reared insects from the galls in North America, e.g. Hughes (1934), Milne (1940) and Ping (1915). Snyder (1898) described the emergence of an adult fly from a gall in Illinois. In Canada, insects have been reared from galls collected in Manitoba and the Northwest Territories by Brodie (1892), in Quebec by Fyles (1894) and in Ontario by Harrington (1895). An opportunity has been taken recently to examine specimens reared by Dr. G. Beall from galls collected at Chatham, Ontario in 1930 and to rear insects from galls in the vicinity of London, Ontario.
