Lately, in the northeastern United States, entomologists and regulatory personnel have found non-native insects with increasing fequency. In Connecticut, new exotic insects are found at a rate of more than two per year. Several newly discovered aliens could have an impact on agriculture.

In the past decade, the author has discovered exotic insects in all the major orders. This poster emphasizes the distribution, the host range, and the seasonal activity of a spruce needleminer, Batrachedra pinicolella (Lepidoptera: Batrachedridae), from Europe, the green pug, Pasiphila rectangulata (Lepidoptera: Geometridae), from Europe, a barberry fruit fly, Rhagoletis meigenii (Diptera: Tephritidae), from Europe, and the giant resin bee, Megachile sculpturalis (Hymenoptera: Megachilidae), from Asia. The discovery of B. pinicolella in the northeastern United States represents a new record for North America. Other new insects finds from abroad are also briefly summarized.
