If you can tell us where your specimen was found, we can start the key with the most likely species near the top of the list.

Do you want to include information on species distribution and abundance?

Yes, give extra weight to species found near a location
chosen from a map

No, do not give extra weight to species based on their location
do give extra weight to all common species
treat all species equally
