In our ‘meadow’ area, back by the woods, there are a couple species of St John’s wort growing; the common St John’s wort, and the larger Kalm’s St John’s wort. The Kalm’s St John’s wort is large enough to be called a shrub, and has been covered with bees foraging on its flowers.
I recently got a couple new colonies of honey bees. These were nucleus colonies, which are just tiny honey bee colonies in small (and more portable) boxes. They rapidly outgrow such small boxes, so moving them into new boxes (and looking them over and taking photos while I was at it) was my first task. Here’s a bit of what I encountered.
The black background to these photos is foundation, a template that the bees construct their comb on inside the hive. Foundation is a sheet of wax, or plastic (or wax coated plastic) printed with a hexagon pattern that the bees draw out into comb. In this case it is black plastic, which is often helpful for beginners to be able to see the bee eggs and young larvae, which is useful in assessing the health of the colony. (You actually literally have to train your eyes to see them; I had good eyesight and knew what I was looking for when I started, but I simply wasn’t able to see them through my veil so I would take it off temporarily. Now I can see them just fine through my veil.)
There are at least three different species of wild bees that nest within a few feet of my back door. Most people never notice that they’re there. Most wild bees are solitary, meaning that they don’t live in colonies. Instead, the female bees build nests and provision them with nectar and pollen and lay an egg or eggs in them. Two of the three outside my back door are solitary, but one is social, meaning that they do live in a colony and even they are very discreet.
The first bees I noticed nesting outside the back door were two-spotted bees, or melissodes bimaculata, as I usually think of them. (I didn’t learn the common name when I first identified them, and I assumed they probably didn’t have one since most common names for bees don’t refer to a single species; they refer to a group of related species. A year or two later, I came across the common name.) These bees have been nesting in the vicinity of the back door since we moved here, which means they’ve probably been there longer than that. Two-spotted bees are solitary bees that nest in the ground and emerge late in the year (I have not even seen any of them yet this year). They usually start to appear at about the time our lemon balm starts to flower, and I frequently see them foraging on it. They are named for the two rectangular spots on the back of the abdomen of the females (bimaculata also means two spotted).
The next bees I noticed were the leafcutter bees. They are not nearly as consistent about nesting in the same spot every year, but there was at least one nest three years ago, and several nests this year that I’ve observed. They’ve certainly been around other years, but I wasn’t able to spot exactly where they were nesting. Leafcutter bees are also solitary, and they build their nests out of pieces of leaves that they collect. They roll the leaves up into a tube, and divide the tube into sections that each will contain one egg and its food provisions. I enjoy watching them forage since they and the other bees in their family are the only bees to store the pollen they’ve collected on the underside of their abdomen, often causing them to hold it up high so that the pollen they’ve collected doesn’t get brushed off.
The third bees to make their nest right outside my door are the bumble bees. These are social bees, and there is one colony living at the edge of the lemon balm patch. They live underground and there is no obvious hole leading to their nest, so they are basically invisible… much like the other bees in this list. I think I was expecting them to be slightly more noticeable since they are social, and honey bees and yellow jackets (a social, sometimes ground nesting wasp) are both fairly noticeable. Both have a steady stream of traffic at their entrance and the yellow jackets do have a noticeable hole when they nest in the ground. But the bumble bees have one or two bees coming and going every few minutes and nothing to see to indicate they’re there otherwise.
Bumble bees spend the warm months of the year living as a colony, and in the fall they raise a new batch of queens which hibernate over winter and start new colonies in the spring. The old queen and colonies don’t overwinter. Because of this, the colonies are in different locations each year.
