Description
Climate change has led to phenological shifts for many taxa. Using light trap data documenting moth communities in 1919 and 1922 in Ithaca, NY, historic moth phenology was compared to current iNaturalist observational records for Tompkins County, NY. It was hypothesized that warming temperatures over the last century would result in earlier emergence of the first brood, longer flight periods, and more generations per year. The week in the year that a species was first seen, climaxed, and last seen for each species that was observed historically in both 1919 and 1922 was recorded. Moth species have experienced a shift to longer flight duration, and are active later in the year than historically observed. Species with plastic voltinism experienced an increase in broods per year. The local extirpation of six species was also observed. Global change associated with temperature shifts is likely influencing the flight periods of moths in the northeast.
