Scolioneura vaccinii Smith & Eiseman, sp. n., is described. It was reared from blotch mines in Vaccinium parvifolium Sm. (Ericaceae) collected in Washington State, USA. This is the first known native species of Scolioneura in the Nearctic Region and the first known sawfly leaf miner of Vaccinium as well as the order Ericales. Characters are given t...
Article
Full-text available
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. Based on...
Article
Full-text available
The genus Liriomyza Mik (Diptera: Agromyzidae) is a diverse and globally distributed group of acalyptrate flies. Phylogenetic relationships among Liriomyza species have remained incompletely investigated and have never been fully addressed using molecular data. Here, we reconstruct the phylogeny of the genus Liriomyza using various phyloge-netic me...

Conference Paper
Microlepidoptera are often underrepresented in biodiversity surveys because they are missed by typical collecting techniques or because adults are small and difficult to identify. Leafminers, which include about 10% of described Nearctic Lepidoptera, are best surveyed by searching vegetation for signs of larval feeding (mines). Most are highly host...
Conference Paper
In March 2017 we took a short road trip through the southwestern United States to enhance the coverage of that region in a guide to North American leafminers. Although winter / early spring in an arid region might seem unlikely to be productive, we found mines of Acanthopteroctetidae, Batrachedridae, Bucculatricidae, Coleophoridae, Cosmopterigidae,...
Article
Full-text available
Phytosciara greylockensis, new species (Sciaridae), is described from Mt. Greylock in western Massachusetts, USA. Larvae are initially leafminers on Clintonia borealis (Aiton) Raf. (Liliaceae), later feeding on leaves externally. DNA barcodes of the new and most other Phytosciara species are presented.
Conference Paper
A focus on the evidence left by certain herbivorous insects, such as galls and leaf mines, can reveal otherwise overlooked biodiversity. In many cases these persistent signs on plants are sufficient to identify the species that caused them. We surveyed the islands of Nantucket and Tuckernuck, MA, for galls and leaf mines, collecting those that we c...

Since 2011 I have been inventorying the gall-making and leaf-mining insects of Nantucket Island, Massachusetts, USA, and have been attempting to rear those whose identities cannot be confidently determined from the galls or mines. Recently I have begun rearing other poorly known herbivorous insects such as free-living sawfly larvae and leafrolling and -tying microlepidoptera. In addition to publishing papers to document new discoveries resulting from this work, I am gradually updating the annotated list of Nantucket's insect fauna compiled by Johnson (1930).
Project
Host plants are only known for about 25% of North American sawflies. I am collecting and rearing larvae with the hope of filling in some gaps. Eventually I would like to compile host data for all North American species in an organized fashion, perhaps with keys to the larvae found on each plant.
Project
I am compiling natural history information for all known North American leafminers into a book that includes dichotomous keys to the mines occurring on each host plant genus, as well as an overview of each group of leaf-mining insects.
