Spilosoma Congrua

I have found the discussion of the identity of Spilosoma congrua, originating with the article by Rev. Dr. Fyles, most interesting, and am tempted to record certain facts not in consonance with the published views of the gentlemen who have already written.Dr. Fyles appears to argue that cunea may be congrua. He tells us, speaking of textor, that there is one brood in his locality usually spotless and measuring 14 lines, and then states that “southward there is a second brood of textor noted for its variations, this being supposed to be the cunea of Drury.” He then refers to Prof. Riley's figures of cunea (Forest Insects, page 245), and declares that with his series of bred specimens of congrua he can match all of Prof. Riley's figures in maculation, and especially in size.

Spilosoma Congrua

To make my way clear I beg to state the objects I had in view in writing the article that appeared under my name in the number of the Canadian Entomologist for last May. They were these:I.—To establish the identity of the Spilosoma Antigone of Strecker with the Spilosoma congrua of Walker.II.—To show that Dr. Riley's series of wings in Fig. 87, Packard's Forest Insects, does not afford a proof conclusive that cunea, textor, punctata and punctatissima are one and the same species of insect.III.—To bring into notice a Spilosoma which answers to the figure given by Drury of his Bombyx cunea.

Needle Blight

BC’s forests have already faced two simultaneous, globally significant, epidemics linked to climate change; the Dothistroma needle blight epidemic in NW BC and the massive mountain pine beetle epidemic throughout the BC Interior. Building on these experiences, we have compiled our best estimates of how we believe other forest health agents may behave as climate change continues to influence our forests. We have drawn on literature from around the world but have focused on the situation in BC. We have made management recommendations based on what we have seen so far and what we expect to come.Key words: climate change, forest health, forest insects, forest pathogens, forest management, British Columbia

In Trans

In reference to the present controversy my testimony is as follows: I examined, in 1867, Mr. Walker's material. This represented a form unknows to me, undoubtedly a Spilosoma, not a species or form of Hyphantria. I was so struck with this that I drew up a description and carefully compared the palpi and antennæ. From these and the slightly larger size, I felt confident that it was a Spilosoma unknown to me at the time. The description is published in Trans. Am. Ent. Soc., 1868, but I have no copy, unfortunately, at this writing, of the paper. My memory is vivid that I compared it with Hyphantria cunca, and it was not that species nor any form of it. I conjectured even, at the time, that the material might be European with a wrong locality, so dissimilar was it from S. virginica or S. latipennis, the latter form being known to me from Stephen Calverley's collections from Long Island before, long before its description by Stretch.
