Key to larvae of Exoteleia species in Ontario
1. Crotchets on anal proleg in a single uninterrupted series of 8-14 (Fig. 8)
-------------________________________________________________________ dodecella
Crotchets on anal proleg in two series of 1-3 situated near each lateral edge of proleg (Figs. 7, 9)_________________________________________________ 2
2. SV setae on abdominal segments 1, 2, 7, and 8 usually numbering 2:3:2:1
(Fig. 11); anal proleg usually with a single crotchet near each lateral margin
(Fig. 7). _________________________________________________________ nepheos
SV setae on abdominal segments 1, 2, 7, and 8 usually numbering 1:2:1:1 (Lindquist, 1963); anal proleg with usually a pair of crotchets near each lateral margin (Fig. 9). ________________________________________ pinifoliella
Key to pupae of Exoteleia species in Ontario The pupae of nepheos and dodecella are not readily separable, except by colour, although they are distinct from pinifoliella. The following key attempts to separate the three species:
1. Pupa near black, in the needle mine; cutting plate present on frontal area of
head (Bennett, 1954) ____________________________......„„ ____ pinifoliella
Pupa yellow-brown or red-brown, in buds or flowers; cutting plate absent ___ 2
2. Dark red-brown pupa; anal end tending to be notched (Martin, 1959) „ dodecella Yellow-brown pupa; anal end not notched (Fig. 10) ________ ______ nepheos
Acknowledgments We wish to thank Mrs. Zena Faux for her assistance in the preparation of the figures, and Mr. George Cruikshank of the Ontario Department of Lands and Forests, St. Williams, Ontario for providing a winter collection of study material.
