Leaf mine.
Chambers (1871a)
described the characteristic upper-surface mine of this species (
Figs. 68–69
) as follows: “Small, circular or ovate, brownish, mottled with whitish; not visible underneath until the lower cuticle dies.”
Braun (1908)
characterized it as “white, densely speckled with dark brown”, which is in agreement with our observations.

Review.
Chambers (1871a)
reared this species from
Tilia americana
in
Kentucky
.
Braun (1908)
stated that it is common throughout the Atlantic states. Specific records include
New York
(
Forbes 1925
),
Ontario
(
Yoshimoto 1977
),
Maine
and
New Hampshire
(
Brower 1984
),
Illinois
(
Godfrey
et al
. 1987
),
Connecticut
(
Maier & Davis 1989
),
Vermont
(
Grehan
et al
. 1995
), and
Quebec
(
Handfield 1997
). CSE has found leaf mines in
Massachusetts
(Montague, Franklin Co.), and they have been photographed in
Michigan
(Orchard Lake, Oakland Co.;
Megachile 2019
).
Comments.
Godfrey
et al
. (1987)
listed adult collection dates in
Illinois
ranging from 6 May to 1 July.
Maier & Davis (1989)
reared adults from mines collected on 9 July and 15 September and stated that their evidence indicated two generations per year. A leaf mine CSE collected in
Quebec
on
8 July 2018
yielded an adult three days later (
Fig. 70
).
