Bee Byte: Can you #WildID a Bee?

On Twitter, nature-lovers will send scientists photos of an animal asking for a #WildID – or species identification. But can you #WildID a bee?

The answer: sometimes yes (but usually no).

Often bees of the same genera will look very similar (for example these two different species of male Agapostemon):

And sometimes, two bees of the same species will look very different (like the abdominal coloration of these two female Augochloropsis metallica):

This makes telling a bee’s species from a photo very difficult; sometimes the features an entomologist must look at to ID a species are hidden under hairs, or even involve dissecting the bee.

However, sometimes a photo with location data can tell us everything we need to know to #WildID – some species have very distinctive features (especially when we know where the photo was taken, and thus what species are in that range). For example the triangle of black on the thorax of Bombus franklini (featured here), combined with information about the bee’s range, can be used to ID B. franklini with relative certainty. Sometimes even the time or flower a bee was spotted on can help #IDthatBee – if it is an early dawn forager, or a pollen-specialist that only visits a specific species.

Don’t be afraid to #WildID your next bee photo – even if the experts can’t get the species, often the next best thing (genera) can be ascertained with a glance. Check out Bees in Your Backyard to try your hand at IDing to genera, yourself!
