With only 8 known localities, Osmia conjunctoides Robertson is a rare species; in the last 30 years it has only been found at one locality in FL (in 2001), prior to that the most recent record was from 1983. Thus this specimen, collected in 1988 likely represents the second most recent collection event for this species, and the location (Archbold Biological Station, Highlands Co., Florida) would be a new locality. #RareBees #MasonBees #BeesOfMastodon #bees #speciesatrisk
