• Pachygnatha autumnalis

  Big-eyed Thick-jawed Spider

  Pachygnatha autumnalis is a long-jawed orb-weaver spider in the family Tetragnathidae, first described by Marx in 1884. The species occurs across a broad North American and Caribbean range, including the United States, Canada, and Cuba. As a member of the genus Pachygnatha, it shares the characteristic robust, enlarged chelicerae that distinguish this group from other tetragnathids. Observations suggest it is primarily active during autumn months, consistent with its specific epithet.
