Bembidion corgenoma
Bembidion corgenoma is a small ground beetle in the family Carabidae, described by David Maddison in 2020. The species was named in honor of former California Governor Jerry Brown and his wife Anne Brown, following its rediscovery on their Colusa County ranch after a 55-year absence from scientific observation. The beetle was previously known only from 21 historical specimens collected between the 1920s and 1966, suggesting a significant population decline likely driven by habitat loss from urbanization and agricultural development in California's Central Valley and Los Angeles Basin.
Epeoloides pilosulus
Macropis Cuckoo Bee
Epeoloides pilosulus is one of the rarest bees in North America, an obligate kleptoparasite of oil-collecting Macropis bees (Melittidae). It belongs to the tribe Osirini, a group of parasitic bees entirely dependent on oil-collecting bees as hosts. The species was thought extinct from the 1950s until its rediscovery in Nova Scotia in 2004, with subsequent records from Alberta, Ontario, Connecticut, Maine, New Hampshire, and Michigan extending its known range. Its survival depends on a three-way ecological relationship: E. pilosulus requires Macropis host bees, which in turn require oil-producing Lysimachia flowers for larval provisioning.
Polystoechotes punctata
giant lacewing
Polystoechotes punctata is a giant lacewing in the family Ithonidae, reaching up to two inches in length. The species was considered extirpated from eastern North America by the 1950s but was rediscovered in Fayetteville, Arkansas in 2012 when an individual was found on a Walmart facade. The specimen was misidentified until 2020. The species shows evidence of a distributional shift, with eastern populations declining and western populations becoming more prominent.
