Ypsolopha dentella is one of three species of Ypsolopha
known to occur in the Ottawa area (J.D. Lafontaine, pers. comm., 2001). My
thanks to Dr. J. Donald Lafontaine for his assistance with this identification.
The forewing of Ypsolopha dentella is mainly a rich warm
brown, somewhat paler toward the costa. From the white top of the thorax,
there extends a streak of pale yellow, edged in white. About two-thirds of
the way along the wing, the white edge line heads off at an angle to create a
spur pointing outwards and upwards towards the costa. Past this spur, the
yellow area is heavily dusted with gray brown, so that the outer third of the
wing is predominantly brown. The upturned tips of the forewings seem to be
a distinctive characteristic of Ypsolopha species. The hindwing is
brownish gray. The wingspan is in the order of 20 mm.
According to a variety of Internet sources, the larval food
plant for Ypsolopha dentella is honeysuckle.
My records to date for Ypsolopha dentella (each date
representing "the night of") are in the table below:
