Ever seen the male longhorned bees, Melissodes agilis, zipping around your garden, trying to bump all critters, large and small, off of "their" blossoms? They own them, ya' know. These male bees are SO territorial.

What you do with firewood this upcoming 4th of July (and year-round!) can impact more than just the s'mores on your campfire. If you move firewood around the state, you could spread deadly plant diseases and invasive insects. Don't take firewood with you if you travel or camp this holiday weekend.

Don't expect to see UC Davis distinguished professor emeritus Art Shapiro monitoring butterflies on the 4th of July. There's a good reason why. Shapiro has monitored the butterfly populations of central California since 1972 and maintains a research site at https://butterfly.ucdavis.edu.

So there it was, an exotic-looking bug resting against a freshly painted red bollard at a Vacaville supermarket. It was not there to shop. Or to stop vehicles from crashing into the store or colliding with shoppers. It was there, I suspect, because of the pheromone-like scent of the fresh paint.

Have you ever seen the digger bees on the sandy cliffs of Bodega Head, Sonoma County? if you hike a short distance up a meandering trail, you'll see a landscape of turrets, the work of solitary, ground-nesting digger bees, Anthophora bomboides standfordina. The nests remind us tiny sandcastles.
