Squash flowers and squash bees

I "surprised" a number of bees this morning in flowers of my vining Tromboncino squash, a Cucurbita moschata cultivar. I vaguely recalled that squash had specialist bees, and had fun finding out more about them. Early in the morning is when squash bees visit flowers (these actually looked like they spent the night). Squash bees are native bees that specialize in flowers of Cucurbita plants -- zucchini, winter squash, pumpkins, etc. They forage early in the morning, collecting nectar and pollen from both the male and female flowers.
