It's the Fourth of July and what better time to post images of the aptly name "soldier beetles" than today.
These insects (family Cantharidae) resemble the uniforms of the British soldiers of the American Revolution, which is apparently how their name originated. They're also called "leatherwings" in reference to their soft, leatherylike wing covers.
Like lady beetles, aka ladybugs, these soldier beetles make short work of aphids and other soft-bodied insects. We've seen them devour so many aphids on our plants that they should be awarded the Aphid Belt, similar to Joey Chestnut's famed Mustard Belt.

If Cinderella were a butterfly, she'd probably be a white cabbage butterfly, Pieris rapae.
The butterfly--in its larval stage it's a pest of cucurbits--is stunning as an adult. Just think of a flowing white gown, exquisite pirouettes, and a flutter like no other.
If you've ever tried to photograph a white cabbage butterfly, it's not all that easy. They are fast and fleeting. One minute they're on the lavender and the next minute they're not. One minute they're on the catmint and then...
