Yellow Dragon

This yellow dragonfly is one of the most striking I have yet to see. Tucson, AZ.

Yellow-Bellied Marmot

Allowing me to get absurdly close, this mama marmot must have really, really enjoyed having her pic taken! Grand Teton NP, Wyoming

Zebra Swallowtails

During a camping trip in Lake Louisa State Park (Florida), the zebra swallowtail butterflies were everywhere, but this was the only linked pair that I encountered. They were content to rest peacefully on a plant stalk, while I snapped all the pictures my heart desired.
