Mill. (

. We have seen leaf mines likely referable to this species on
S. altissima
L. and
S. macrophylla
Banks ex Pursh.
Leaf mine.
Whitish, on the upper surface, narrow and linear throughout; frass typically in fine particles, mostly forming short beaded strips, but in some cases mostly deposited in an erratic jumble of squiggly fragments, rarely appearing as straight strips for a very short stretch (
Eiseman & Lonsdale 2018
).
Puparium.
Black; formed outside the mine.
Phenology and voltinism.
As discussed by
Eiseman & Lonsdale (2018)
, this species is thought to be univoltine in
Alberta
, where larvae collected in early August and late September emerged as adults the following spring, but it is at least bivoltine in
Massachusetts
, where larvae collected between 9 and 12 June emerge as adults by the end of the month, larvae collected in late July have yielded tentatively identified females in mid-August, and larvae of the overwintering generation have been collected in early October.
Distribution.
USA
: MA, WI?;
Canada
: AB (
Eiseman & Lonsdale 2018
). We have found leaf mines likely referable to this species in IA and MI.
