All three photos are of the same specimen.
Catastega timidella, at one time classified as Epinotia
timidella, is one of two species of Catastega that have been recorded
from the Ottawa area. My thanks to Dr. Jean-François Landry of
Agriculture Canada for identifying the specimen illustrated above, which was
collected and given to the Canadian National Collection in Ottawa. This
specimen has also been included in the All Leps Barcode of Life project of the
Biodiversity Institute of Ontario at the University of Guelph. Additional
information has been obtained from Internet resources, from Brown, R.L. (1986),
"Resurrection of Catastega Clemens and revision of the Epinotia
vertumnana (Zeller) species-group (Tortricidae: Olethreutinae)," J.
Lep. Soc., vol. 40, no. 4, pp. 327-346 and, under the name Epinotia
timidella, from Forbes, William T.M., The Lepidoptera of New York and
Neighboring States, Primitive Forms, Microlepidoptera, Pyraloids, Bombyces
(Ithaca, New York: Cornell University, 1923).
The forewing of Catastega timidella is blackish to
grayish in the costal half, with a large whitish area along the inner margin,
the boundary between dark and light areas forming a broad lengthwise
zigzag. A short grayish bar at the inner margin just before the anal angle
includes several small black streaks. The area along the costa is somewhat
striate, especially towards the apex. The thorax is light dusty gray, but
the head is white. Forbes (1923) indicates a wingspan of 18 mm.
According to Rings and Metzler (Rings, R.W. and Metzler, E.H.
2002. The Lepidoptera of Portage County, Ohio. OARDC Research
Bulletin 1195; available on the Internet), the larvae of Catastega
timidella feed in serptentine tubes on the undersides of oak, birch and
walnut leaves. Brown (1986) and Forbes (1923) refer only to oak as a host
plant. According to Forbes (1923) and RIngs and Metzler (2002), the adult Catastega
timidella flies in May.
