The effect of the 20th-century functional extinction of the American Chestnut (Fagaceae: Castanea dentata (Marshall) Borkh) on associated herbivorous insects is unknown. These insects include leafminers that spend at least part of their larval phase feeding between the epidermises of leaves. We surveyed leafminers on C.

The leafminers on gymnosperms receive much less attention than those on either angiosperms or ferns. Given the distinctly different leaf shape and leaf venation found in gymnosperms, they would be expected to host significantly different leafminer groups. Very few comprehensive reports on gymnosperm-feeding leafminers have been presented.

We describe leaf mines or other larval habits for 27 species, plus five others whose identification is tentative, and another five that are identified only to genus due to the absence of male specimens. We review host and distribution data for the known species, reporting 26 new host species records (including the first rearing records for Phytomyza flexuosa Spencer, P.

The erection of this genus has become possible now that monophyly has been supported by a recent phylotranscriptomics analysis. Six species are combined in this genus: (van Nieukerken & Wagner, 2012), , (Chambers, 1874), , (Chambers, 1874), , (Braun, 1927), , (Braun, 1927), , (Clemens, 1860), and two candidate species are recognised.

Typically, species of Cameraria form flat mines on the upper leaf surface, whereas most Phyllonorycter species form underside tentiform mines. We reviewed North American literature records and found 15 exceptions to this generalization, with two Cameraria species reported to form underside mines and 13 Phyllonorycter species reported to form upper-surface mines.

These include Grapholita thermopsidis Eiseman Austin, new species, which feeds on Thermopsis rhombifolia (Pursh) Richardson (Fabaceae), along with two others for which larval hosts were previously unknown: Catastega triangulana Brown (Ericaceae: Arctostaphylos pungens Kunth) and Sparganothis xanthoides (Walker) (Polemoniaceae: Phlox divaricata L.).

To understand how such organisms proceed through development, we examined the timing and prevalence of mortality among embryos of unisexual salamanders in the genus Ambystoma.
Results: Our regional field surveys suggested that heightened rates of embryo mortality among unisexual salamanders begin in the earliest stages of embryogenesis.
We present novel rearing records of Agromyzidae (Diptera) from throughout the United States. We describe leaf mines or other larval habits for 14 species, plus three others that could not be confidently identified in the absence of male specimens. We review host and distribution data for the known species, reporting 14 new host species records (including the first rearing records for Cerodontha (Dizygomyza) magnicornis (Loew)) and 12 new state records (including the first USA record for Phytomyza prava Spencer).

These include the first reported host for Calycomyza novascotiensis Spencer (new to the USA) and new host records for Ophiomyia beckeri (Hendel) (new to North America), Liriomyza helianthi Spencer, L. schmidti (Aldrich), and Phytomyza plantaginis Robineau-Desvoidy, all of which are reported from North Carolina for the first time.

We describe a new species, M. viburnella Eiseman & Davis, which feeds on Viburnum, initially mining the leaves but completing development as a stem miner.

This approach can be extended to include species with temporally variable detection probabilities. By concentrating survey effort in years when the focal species are most abundant or visible, overall detection rates can be improved.
