Chrysoclista linneella has orange wing colour surrounded with black; 3 silvery spots.
Mompha terminella has dark wing tips and large, black tufts at mid-wing.
Euclemensia bassettella has a wide black inner margin from mid-wing to tip. Antenna last 1/3 white.

Size: 7 to 8 mm long. Wingspan 10 to 13 mm.

Habitat: Meadows and forest edges.

Food: Wild Four O’clocks Mirabilis nyctaginea.

Flight Time: Mid-May to early June; mid-July to early August; partial 3rd generation late August to early September in Ontario.

Life Cycle: Females lay white, flattened eggs on the underside of Four O’clock leaves, usually at the base of the plant. Larvae burrow into underside of leaf and feed internally, often with more than one larvae in a leaf. By the 3rd instar, they move to the exposed underside of the leaf and feed under a silken web. The feeding creates white ‘windows’ on the upper side of the leaf.
The larva is pale green with a blackish head and two dark spots on shield, later blending into one large spot. Over-winters as a pupa. Two generations and a partial 3rd generation.
