As the invasive spotted lanternfly continues to expand its range in the eastern U.S., a new study on the temperatures it needs for progressing through its life cycle offers a clearer picture of where the spotted lanternfly is likely to thrive—and where it's not. In short, northern ranges and higher elevations could escape its impacts.
The western U.S. is home to two known native species of subterranean termites, Reticulitermes hesperus and Reticulitermes tibialis. But a new analysis shows R. hesperus is likely a species complex of at least two distinct species, and at least five species Reticulitermes in all may be present in California. A better understanding of these separate subterranean termite species and their behaviors will be essential for effective management.
The increasing volume of insect photo observations shared on iNaturalist and similar sites can no longer be ignored, and entomologists are finding ways to use it. A review in Annals of the Entomological Society of America digs into best practices for bolstering entomological research with this growing body of citizen-science data.
A trio of entomologists at the Illinois Natural History Survey tackled a backlog of hover fly specimens dating back a century, digitized them, and combined them with online databases—leading to several new species records, changes to species ranges, and even discoveries of new areas of conservation concern for hover flies in the state.
