Agapostemon sericeus, M, back, Pr. Georges Co., MarylandMale Agapostemon's almost all have this same pattern, Metallicy green on the head and thorax and then striped yellow and black on the abdomen. Females uniformly don't have yellow anywhere. Why is good question as this male yellowness syndrome runs throughout the bee kingdom, cutting across families.
