    ugly-nest caterpillar moth

    Archips cerasivorana, commonly known as the ugly-nest caterpillar moth, is a tortricid moth species distributed across North America from Alaska to North Carolina. The species is notable for its highly social larval behavior: caterpillars construct large communal silk nests by tying host plant leaves together, and they communicate through trail-following pheromones released from their spinnerets. Adults display distinctive orange forewings with silvery bars and a wingspan of 20–25 mm. The species has one generation per year, with adults active from July to September.
