Agapostemon sericeus, M, side, Pr. Georges Co., Maryland
Male 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. Thistle Droege did the photoshoping and Wayne Boo the photography.
The murmuring of bees has ceased;
But murmuring of some
Posterior, prophetic,
Has simultaneous come,--
The lower metres of the year,
When nature's laugh is done,--
The Revelations of the book
Whose Genesis is June.
