Agapostemon on Tradescantia ohiensis
Little is known about Sphecodes prosphorus, but the Sphecodes are kleptoparasites of other Halictids (including this Agapostemon sericeus), so I thought it would be interesting to compare their phenologies. Their interactions segregated by plant species, so Sphecodes is in teal and Agapostemon is clear. You can also compare this phenology to Agapostemon virescens.
