June fireflies and tree frogs

My gardening companion just reported seeing fireflies, about at mid-canopy in the surrounding forest.

They're the first, aside from a few that appeared after a brief warm spell in May. We had a thunderstorm this afternoon, but not a lot of rain.

When I went out to look, I didn't see fireflies, but heard the trills of tree frogs and night insects.

Summer is almost here.
