Hi Linda,
The western grass skippers can be very confusing.
As to iNaturalist, a lot depends on the animal family. It can be spotty [excuse the pun] on butterflies and mammals like chipmunks, but if you do dragonflies, Dennis Paulson's IDs are timely and flawless.
Enjoyed your presentation at the annual meeting [where we no longer do manual eating]. It's hard to do a pot luck on Zoom.
Cheers,
