🦋 It’s National Pollinator Week! 🐝🦇
By Julia Wine, Girl Scout
Several species of solitary bees, including Blue Orchard bees and Japanese Horned Mason bees live in our part of Northern Virginia. These bees don’t live in social hives but make their nests on their own. They very rarely use their stingers because they are not defending a collective hive filled with honey. They lay their eggs in hollow stems or already existing holes in trees or dead wood, sealing in each egg with a layer of mud.
A solitary bee’s method of pollination is also different from a honeybee’s. Instead of carrying pollen in baskets on their hind legs, they collect pollen with the hairs on their underside, making the pollen more likely to make contact with a flower for pollination.
Solitary bees are experiencing population declines and range reductions due to a number of factors. Habitat loss and fragmentation of population groups decrease the availability of nesting sites so the bee population can’t grow. Pesticide use has harmful effects on bees and can kill them. Competition with honey bees reduces the amount of resources available for solitary bees. All of these factors negatively affect the population of solitary bees.
To combat habitat loss affecting solitary bees, I decided, as a Girl Scout project, to build a bee box and, and with the guidance of local Virginia Cooperative Extension Agent Kirsten Conrad and Natural Resources Manager Alonso Abugattas, installed it in the Master Gardeners Teaching Garden behind the Fairlington Community Center. This project earned me Girl Scouting’s highest award, the Gold Award.
Building a bee box is a fairly straightforward endeavor. To build this one, I first built the exterior box out of 2 x 12 wood boards and painted it with primer and then beige exterior paint. The interior blocks of wood were cut from a 4 x 4 cedar post and drilled with holes 5/16th of an inch in diameter and 3⁄4 of an inch apart. Next, I cut dried bamboo into pieces separated by their nodes so that each one had an open and closed end. I placed the cedar blocks and the bamboo pieces inside the box. To install, I hung the box on the garden’s steel trellis facing east so that the bees get morning sun.
This box will provide a place to nest for the nearby population of solitary bees for many years to come. The project will serve as a resource for the Fairlington Community Center teaching garden so local residents can learn more about solitary bees and perhaps copy this example and help reverse habitat loss by building a box of their own.
