The partridge pea (Chamaecrista fasciculata) at south Oslo Riverfront Conservation Area was ablaze with flowers when we took a very small-group walk to look for Florida butterfly orchids (Encylcia tampensis) on June 27, 2020.
Bees pollinate this native annual via sonification, a.k.a. buzz pollination. I could hear the buzzing and assumed and that a bumblebee was the pollinator, but I was wrong.
George and Mary Ester Bollis sent photos of the southern carpenter bee (Xylocopa micans) that was pollinating this plant …
When I looked at my photos, I saw that the pollinator was indeed a carpenter bee. Carpenter bees are native and solitary. They rarely sting unless molested. Yes, the females will create nests in unpainted wood but otherwise they use twigs — or bee boxes — for their nests.
