samwilhelm's Identifications

This is a large (15 mm) female Andrena found feeding on farkleberry (Vaccinium arboreum) growing near a wooded area north of Gainesville. The remarkable things about this bee are its size, black wings and intensely orange color. Its legs (except for the coxae and trochanters) are orange-red, and bright orange hairs cover much of the head, thorax and legs. This female was found together with the male bee shown here: https://www.inaturalist.org/observations/207778469

I have seen this species in three different locations of Alachua County during April 2014. The University of Florida bee key notes that Andrena obscuripennis has been found previously in Alachua County: the Bee Library records specimens at the University of Florida from Alachua Co. dated 1995-1997, and 1949. (See https://library.big-bee.net/portal/collections/list.php?usethes=1&taxa=4966). Bouseman & LaBerge (1978) wrote that Andrena obscuripennis was initially known only from Georgia and North Carolina, but noted that Mitchell (1960) provisionally included New Jersey and Louisiana in its range. The species has since been documented in places as widely dispersed as Mississippi, Missouri and Ontario.
