Cameraria Chapman and Phyllonorycter Hübner (Gracillariidae: Lithocolletinae) are two speciose genera of leaf-mining moths that were once treated as belonging to a single genus, Lithocolletis Hübner. Typically, species form flat mines on the upper leaf surface, whereas most underside tentiform mines. We reviewed North American literature records found 15 exceptions this generalization, with reported 13 upper-surface For each these we summarize published data larval biology, hostplants,...

The effect of the 20th-century functional extinction American Chestnut (Fagaceae: Castanea dentata (Marshall) Borkh) on associated herbivorous insects is unknown. These include leafminers that spend at least part their larval phase feeding between epidermises leaves. We surveyed C. dentata, nonnative spp., and hybrids Long Island, NY. found 10 leafminer species spp. A first New York State record was documented for Stigmella castaneaefoliella (Chambers) (Lepidoptera: Nepticulidae). host...

Abstract The elm zigzag sawfly, Aproceros leucopoda Takeuchi (Hymenoptera: Argidae), was reported for the first time in North America during summer of 2020. Characteristic defoliation province Québec, Canada, on community science website, iNaturalist. Field trips conducted to site resulted collection live specimens (a few larvae and a cocoon from which an adult emerged) onsite observation diagnostic empty cocoons, confirming presence this exotic species Canada. Subsequent inspection trees by...

The paratype series of Megaselia globipyga Borgmeier was found to contain two species, neither which matched the holotype. holotype M. is here fully illustrated for clarity, and new biological geographical data species are given. A risoria Hartop, Wong, Eiseman, described from paratypes globipyga, a original type postcrinata Borgmeier, singleton BioSCAN Project.

Abstract The genus Liriomyza Mik (Diptera: Agromyzidae) is a diverse and globally distributed group of acalyptrate flies. Phylogenetic relationships among species have remained incompletely investigated never been fully addressed using molecular data. Here, we reconstruct the phylogeny various phylogenetic methods (maximum likelihood, Bayesian inference, gene tree coalescence) on target‐capture‐based phylogenomic datasets (nucleotides amino acids) obtained from anchored hybrid enrichment...

Improving detection rates for elusive species with clumped distributions is often accomplished through adaptive sampling designs. This approach can be extended to include temporally variable probabilities. By concentrating survey effort in years when the focal are most abundant or visible, overall improved. requires either long-term monitoring at a few locations where known occur models capable of predicting population trends using climatic and demographic data. For marbled salamanders...
