Surveys of Wild Bees (Hymenoptera: Apoidea: Anthophila) in Organic Farms of Alachua County in North-Central Florida

H. Glenn Hall, John S. Ascher

Abstract


Bee surveys were conducted at 5 organic vegetable farms and 1 wildflower farm in Alachua County in north-central Florida. Wild bees were collected passively with colored cups and actively with nets. A total of 4,662 bees was captured belonging to 28 genera and 95 species. Nomada sulphurata Smith is a new state record for Florida. The species count also includes 6 Nomada and 1 Triepeolus morphospecies which likely include undescribed species and additional new Florida records. Of 5 bee families, Apidae was represented by the most species (36), whereas 6 of the 8 most numerous species were Halictidae. A potential new host cleptoparasite association is reported between Andrena (Melandrena) barbara Bouseman and LaBerge and Nomada imbricata Smith. The results from these surveys of organic farms are compared to our recently reported surveys of bees in natural areas of Alachua County and with other Florida bee surveys. The most numerous species found on the farms were also numerous in the natural areas, whereas the least numerous species on the farms included many species not found in the natural areas.
