Conotrachelus buchanani Schoof, 1942, new to Canada
Species identification confirmed by RSA, 2015
Note.
This native species is associated with
Celtis
L. spp. (
Cannabaceae
) (
Schoof 1942
), specifically common hackberry,
Celtis occidentalis
L., in Quebec. All specimens collected in Montreal were beaten from common hackberry, and all those from Terrasse-Vaudreuil were attracted to a light source located no more than 10 m from a hackberry tree. Hackberry has been favoured as a street tree and planted in great numbers in some boroughs by the City of Montreal between 1972 and 1984 (
QueBio
2016
), obviously
much
to the benefit of the weevil. Records provided herein represent a significant northerly extension of the range of this species which was previously only known from as far north as Pennsylvania (
O'Brien
and Wibmer 1982
).
Specimens from southern USA were examined and found to be consistently larger than the northern forms from Quebec and northern USA, but dissections failed to reveal any further significant differences between the two groups. The status of the Canadian and northern USA forms needs further study. For the time being specimens reported herein will be considered as
C. buchanani
.
