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. We've seen them target honey bees, bumble bees, carpenter bees, syrphid flies, spiders and praying mantises. And one another. Everything is fair game.
"They're saving the flowers for the females of their species, so they can mate with them," according to the late Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor, Department of Entomology and Nematology.
But as dusk...

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.

What a beautiful sight...a yellow-faced bumble bee, a queen, foraging on yellow bush lupine blossoms at Bodega Bay.
She buzzed from blossom to blossom at Doran Regional Park while packing a ball of red pollen that seemed to increase in brilliance with every floral visit.
A native bee, Bombus vosnesenskii, on a native plant, Lupinus arboreus.
B. vosnesenskii queens are larger than the workers. Queens measure between between 18 and 21 mm long, while the workers (females) range from 8 and 17 mm. The males? 10 to 15 mm long.
The yellow bush lupine, which can reach a height of seven feet and a width of four feet, seems to...
