Eastern Carpenter Bee Field Notes:
The notes below describe the mid-spring sighting of an Eastern Carpenter Bee. Additionally, field notes offer lifecycle and habitat information to help identify the bee, and a few fun facts.
- Date & Time: March 25, 2026, afternoon
- Species: Eastern Carpenter Bee (Xylocopa virginica)
- Location: Central Kentucky, herb and vegetable garden
- Weather: Warm, mide 70°F, sunny
Observation:
An Eastern Carpenter Bee hovered on the open bloom of a lavender plant. With its long proboscis extended, the large bee collected nectar and pollen from the tubular bloom. This hovering behavior on lavender plants signifies the transition from the harvest of cold-weather crops like cabbage and broccoli to the blooming of warm-season crops such as tomatoes and squash.
Notes:
This bee was focused on collecting nectar while expending tremendous energy by continuously its flapping wings.

Life Cycle and Habitat
Eastern Carpenter Bees, depending on their region, generally have a long lifespan. Their life cycle begins in early spring when overwintering adults emerge to mate. During this time, females construct nests by building tunnels in wood structures, where they will lay their eggs and care for the larvae. Towards the end of summer, new adults emerge, and the older generation dies. The new generation forages for several weeks before returning to their nests in the fall to overwinter.
Social & Nesting Habits
Eastern Carpenter Bees construct their nests above ground in dead wood or timber. They bore tunnels in wood structures, creating nurseries where their eggs transform into the next generation of adults. While they are generally solitary bees, each living in its own nest, some females will share a nest with a daughter. Additionally, they also can nest in close proximity to one another, forming tightly woven neighborhoods.
Pollen & Nectar Sources
(Cercis canadensis)
common- Bee Balm
Eastern Carpenter Bees, the generalists, forage for a diverse range of flower species. While they visit numerous flowers, they have a particular fondness for the Eastern Redbud. This redbud serves as a crucial, early-spring nectar source for them. Additionally, they are attracted to the nectar and pollen on Salvia and Bee Balm, and they are excellent pollinators of blueberry crops.
