Moth communities as indicators of environmental changes:
results from natural experiments along a latitudinal gradient.

Discover Life's Mothing project's scientific objectives are to
understand how weather patterns, urbanization, and latitude
affect moth communities.  Since 2010, participants
have photographed 265,000 moths at 16 study sites in the
eastern United States and Costa Rica, documenting nightly
differences in the seasonal activity and abundance of over
2,400 species across years and sites. Novel results show how
body size of a species can change between generations and
years; how smaller moths are relatively less active than
larger moths at colder temperatures, and how moths with
larvae that feed on lichens may be more detrimentally
affected by urbanization than other species.  For details
