Learning about native bees.

Another occasional reminder that phoretic mites come in sizes appropriate to their bees. This little Halictus tripartitus has a single tiny pink mite on her eye. The mites hitch a ride to the nest where they act as a cleanup crew. [Alameda, CA 7-17-26] #bees #nativebees

Speaking of finger sizes… This tiny Bold Jumping Spider earned his or her moniker by not retreating from the enormous thumb looming ever closer. Thank you for your heroic contribution to Thumbparison Science! [Alameda, CA 7-17-26] #spiders

We all often see male European Wool Carder bees fighting for turf, but we don’t often see the price - this fellow managed to lose three of his four wings in battle. In fairness the Stachys bush he was on is unusually crowded with males. [Alameda, CA 6-12-26] #bees #nativebees

When Redflower Buckwheat is in full bloom (now, around here), it's insect pandemonium. Normally, you'll see a cuckoo bee occasionally. This bush had so many Nomada cuckoo bees, mostly males, that I got to witness aerial traffic collisions. [Alameda, CA 7-3-26] #bees #nativebees

Why are female Melissodes longhorn bees always in a hurry? Because they deal with crazy traffic like this all the time. Dodging a male longhorn bee... who's being chased by a male Megachile perihirta, Western Leafcutter Bee. [Alameda, CA 5-22-26] #bees #nativebees

Brown yellow and black female longhorn bee on a bright red and yellow Gallardia flower, carrying lots of pale lavender colored pollen, minding her own business. Female longhorn bee flying off the flower just in the nick of down as a male longhorn bee comes clumsily barreling in. The reason for the male longhorn barreling through - here comes a male Western Leafcutter bee, with his distinctive white "mittens" on his front legs. The female longhorn is visible in the top of the frame, flying away. Just the male longhorn bee in front of the flower, with half the female longhorn visible in the upper left of frame. Another turf protecting victory for Mr. Mittens.

Always an unusual sight - a live honey bee drone. They never survive long once ejected from the hive so it must be nearby. I always see them in the same spot. At least he won’t get the indignity of getting stepped on on the sidewalk. [Alameda, CA 5-18-26] #bees
