|scientific name Idaea rotundopennata |
common name Round-winged Wave
Peak flight activity is from mid June to early July.
One of a number of geometrid species which are relatively small and havepale tan or whitish wings. As the common name suggests, the wing margins are rounded, not slightly pointed midway as in similar species of Scopula, including S. junctaria to which Idaea is superficially most similar to.
Larvae likely hibernate, and pupae are attached to vegetation without a cocoon, and supported with a silk girdle much like butterflies (Wagner et al. 2001). Adults come to lights.
Not of concern
The only larval host reported in the literature is Polygonum (McGuffin 1967), but additional low-growing plants are also likely hosts.
Nova Scotia to BC and the Yukon, south to Maine (McGuffin 1967).
