Distribution
fornecido por University of Alberta Museums
This species is native to eastern United States, Quebec and Ontario, but has been found in prairie cities since 1999 (Forbes, 1923). The range is expanding due to urban planting of ornamental Ash trees.

General Description
fornecido por University of Alberta Museums
Caloptilia fraxinella are small moths with 12-14mm wingspan. Wing background is gray; forewings have many black and white scales that form spots (Forbes, 1923). A few orange iridescent scales are scattered across the wing surface. The fringes of hind wings, head and thorax are all gray. Male genitalia show the clearest difference between species of Caloptilia. The valves are lobe-shaped instead of notched near tip of ventral margin as in C. alnivorella and C. strictella (Pohl et al. 2004).

Life Cycle
fornecido por University of Alberta Museums
Small (0.4mm x 0.3mm) white eggs are laid singly along the midrib of newly emerged ash leaves. Within one week the first instar larvae emerges and begins mining under the upper cuticle of the leaflet. Fourth instars will emerge from the leaflets and use silk to migrate to new leaves in late June. The small (7.3mm) cream coloured larvae will roll the distal portion of the leaf under to create a small cone (fig.1). In mid-July the fifth instar will eat away a small circle of tissue under the upper cuticle; this appears as a white 'window' on a rolled leaf. A cocoon is spun with one opening attached to the window and other to the other side of the cone. After 10-14 days of making the window the pupa pushes itself 1/3 out the window and the moth emerges. Adults will aestivate mid-august and re-emerge in September to find overwintering sites. They overwinter until mid-April to mid-May, which is when they mate (Pohl et al., 2004).

Trophic Strategy
fornecido por University of Alberta Museums
Caloptilia fraxinella larvae mine the top side of the leaves of ornamental green ash (Fraxinus pennslvanica), black ash (F. nigra) and Manchurian ash (F. mandshurica) until third week of June. The final instars of larvae create rolls on the ash or neighboring lilac bushes (Syringa vulgaris) (Pohl et al., 2004).

Caloptilia fraxinella: Brief Summary
(
Inglês
)
fornecido por wikipedia EN
Caloptilia fraxinella (ash leaf cone roller moth) is a moth of the family Gracillariidae. It is known from Canada (Québec, Alberta, Ontario and Saskatchewan) and the United States (Michigan, Vermont, Ohio, Connecticut, New York and Maine).
It is considered a significant pest of horticultural ash.
The larvae feed on Fraxinus species (including Fraxinus americana, Fraxinus mandshurica, Fraxinus nigra and Fraxinus pennsylvanica) and Ligustrum species. They mine the leaves of their host plant. The larvae form a typical leaf cone. The species is atypical for the genus Caloptilia in that the larva pupates within the leaf cone, in a suspended silken cocoon. The species overwinters as an adult.
