Megapurpuricenus
Megapurpuricenus is a monotypic genus of long-horned beetles in the family Cerambycidae, established by Eya in 2015. The sole described species, M. magnificus, is notable for its spectacular appearance and highly synchronized emergence pattern. Adults emerge en masse every three years for approximately two weeks following the first summer monsoon rains, creating a brief but intense reproductive window. The genus is endemic to a limited number of locations in the southwestern United States, where it develops as larvae in the trunks of living oak trees.
