Similar to bird watching, bee watching involves observing the local bee population. Taking pictures is a good way of documenting what you’ve seen, and can often be used to identify the bee to species. Regrettably, not all pictures contain clear images of the anatomical features needed to identify the insect positively. Multiple photos are often required for identification (the face, abdomen & thorax are usually needed), though some species require other features such as the vein patterns in wings.

All you need is a camera (cell phone cameras work fine) and a place outside to look for bees. A good place to start is on the plants bees visit to collect nectar and pollen.
