Pollen Specialist Bee Phenology: JULY

Table 1. Pollen specialist bee families (n = 6), genera (n = 24), and species (n = 93) with taxonomic authorities, distributions according to records from 20 states (AL, CT, DE, FL, GA, LA, MA, MD, ME, MS, NC, NH, NJ, NY, PA, RI, SC, VA, VT, and WV), regional conservation status (Common, Uncommon, or Rare), phenology according to records from 12 months (January, February, March, April, May, June, July, August, September, October, November, and December), and host plant families, tribes, and genera. Bee families and member genera and species are presented in ascending alphabetical order; families, subfamilies, tribes, and subtribes link to BugGuide profiles; species link to Discover Life species profiles. Month headings link to month-specific lists. Host plants link to USDA PLANTS Database genera profiles: view 'Subordinate Taxa' tabs for regional host plant species.
