The month of September in my North American Native Bee Calendar purchased from the Great Sunflower Project, features the Longhorn Bee, genus Melissodes.
These bees emerge in late summer and nest in the ground. They are small to medium sized with golden brown hairs over much of their bodies. Both sexes have a fuzzy thorax and noticeably hairy legs. The males are smaller than the females and have particularly long antennae. To view images of Longhorned Bees click here.
Many plants of the Asteraceae family, such as sunflowers, are highly dependent upon these bees for cross pollination.
You might spot a Longhorn Bee if you grow cosmos, blanketflowers, sunflowers, tickseed and beggarticks (Bidens).
In June I featured the Leafcutter Bee. Some of you said you see evidence of Leafcutters on your roses. Well, I just noticed this myself on my swamp rose!
