While most floral visitors will likely be part of one of the four main groups of Claytonia pollinators (Andrena erigeniae, bee flies, small dark bees, or cuckoo bees), there may be visitors from the following groups, as well. Don’t worry if you can’t learn all of these groups – it’s more important that you’re confident about the main four. However, if you do recognize one of these visitors visiting your focal patch, make a note of it!
Green bees will be occasional visitors, especially in late spring. These bees are easily identified by their metallic green color.
Bumblebees (especially bumblebee queens) will also occasionally visit, also in late spring. Bumblebees are easily recognized by their round shape and large size.
Large Andrena. In addition to our pollen-specialist, Andrena erigeniae, other bees in the genus Andrena may also visit. These bees may be hard to distinguish from A. erigeniae, so don’t worry if you can’t tell them apart. However, if you notice a bee similar to A. erigeniae but larger, make a note of it – it might be another Andrena species.
Honeybees. In some areas, honeybees (Apis mellifera) may be common. While they seem to avoid Claytonia flowers, they may visit in some cases.
Other flies – in addition to the common bee fly – may visit, as well. If there is a visitor that has fly characteristics, but isn’t a bee fly, record it as “other fly” – don’t worry if you don’t know what it is, exactly.
