Dr. Andrew Merwin studies insect ecology and insect conservation. He tries to understand the biological and climatic factors that influence the distribution of insects and their traits. For instance, he and a student are currently working on research to track the evolution of spotted lanternflies’ traits as they spread west. He is also working with Dr. Carrie Davis-Todd and colleagues in Nebraska to use bioclimatic variables to predict favorable and unfavorable conditions for the Salt Creek tiger beetle, the nation’s most endangered beetle.

His lab uses spatial and temporal statistical modelling techniques, cameras for imaging specimens, flight mills for quantifying flight, shotgun microphones for recording insect songs, sweep nets, pitfall traps, insect pinning equipment, and just about anything that will help get the job done.

Students with interests in animals and plant-animal interactions are encouraged to send him an email or stop by his office.
