Honey Bee Larvae: Weigh to Go!
It's a week before Christmas and it's not just the geese that are getting fat. If you're thinking that the bathroom scale and you are not good friends, not to worry. We remember the late Extension apiculturist emeritus Eric Mussen (1944-2022) of the UC Davis Department of...

The Butterfly Egg: The Promise of a New Generation
Ever seen a Gulf Fritillary laying an egg? The Gulf Frit, or "passion butterfly" (Agraulis vanillae), lays her tiny, yellow eggs, singly, on her host plant, the passionflower vine (Passiflora). The egg? It's about the size of a pin head. Look closely and you'll see it's ridged like the...

These Beetles Don't Want to Hold Your Hand
The Beatles sang "I Want to Hold Your Hand." The elm leaf beetles and their larvae don't want to hold your hand--unless perhaps you're holding a elm leaf that they can eat. A recent walk down the 200 block of Buck Avenue, Vacaville, California, revealed the damage this pest does. The stately...

Day 2 of National Pollinator Week: Focus on a Tiny Egg
It's Day 2 of National Pollinator Week. So, I guess I should "toot my own horn" (we don't have one, but in our household we do have a piano, a double bass, a guitar, a banjo, a ukulele, a dulcimer, a harmonica, a sousaphone, a set of hand drums, and two accordions. Note that the last...

The Oleander Aphid and the Monarch Egg
You never know about those photo-bombers. You can't trust 'em. So here I was, trying to photograph a tiny egg that a monarch butterfly had just deposited on our milkweed. I held it up for a better look. And then, the photo-bomber! An oleander aphid, Aphis nerii, appeared...
