The aphids know how to plan a family reunion.
Grandma, grandpa, aunts, uncles, mom and pop, brothers and sisters, cousins and more cousins--they're all gathering to feed on the lush growth of the spring roses, the juicy shoots, the tender buds. And they multiply. You think rabbits multiply fast? Try aphids.
A telltale sign of their presence: Crumpled white carcasses and leaves coated with sticky honeydew.
A strong blast of water and the aphids are gone.
Well, at least some of them.
We watched a sole ladybug, aka ladybeetle, feasting on an aphid buffet on Easter Sunday. So many aphids, and so much time. All the aphids on her menu were green, but they come in yellow, brown and black, too.
The aphids crawled along the rose stems, bumping their cornicles or tubelike structures into one another, unaware of the looming red predator in their midst.
Until it was too late.

"Stop and smell the roses."
How many times have you heard that? It's usually from someone urging us to slow down, to savor life, and to pay attention to the pleasures.
Like fragrant roses.
Honey bees seem to be particularly fond of the butterfly rose, also known as the China rose (Rosa mutabilis), a deciduous shrub that can grow up to six feet high and spread five feet across. It's a long flowering plant, especially important to bees when they emerge from their hives after a long cold winter and begin to forage for food.
The butterfly rose, so named because its blossoms resemble butterflies, is cherished for its ever-changing flowers, which turn from yellowish/orange to pinkish/red to a coppery red.
Stop and smell the roses? Yes, but also look for the beauty in the bees.

Laidlaw Jr. Honey Bee Research Facility, is open to the public from dawn to dusk for free, self-guided tours. Plans call for guided tours, for a nominal charge, starting March 1.

What's that? A honey bee and a male yellowjacket on the same blossom?
Honey bees and yellowjackets belong to the same order, Hymenoptera, but different families. The honey bee (Apis mellifera) is in the Apidae family, while the yellowjacket, Vespula pensylvanica, belongs to the family, Vespidae.
When beekeepers open the hives at the adjacent Laidlaw facility, trouble can start between the honey bees and the yellowjackets. It's no secret that female yellowjackets establish their nests near apiaries to prey upon honey bees and their brood. They need the protein for their offspring.
But here they were--the honey bee and the yellowjacket--together.
The first occupant: the honey bee. She began foraging on a rose blossom when suddenly a male western yellowjacket approached her. Seemingly unaware of his presence, she kept foraging. He poked her with his antennae. She ignored him. He crawled up next to her and took a close look at her. She kept foraging.
A few seconds later, he left.
Native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis, later commented: "I can't help but wonder why the male yellowjacket was visiting a rose flower--no nectar there, so no reward for him."
"Maybe he was just checking out the other occupant 'while searching for love in all the wrong places.' "
Indeed, the male yellowjacket may have been looking for a suitable mate.
This one? Definitely not suitable!

Poet Gertrude Stein wrote in her 1913 poem, "Sacred Emily," that "a rose is a rose is a rose."
Things are what they are. The laws of identity. No matter where I go, there I am.
When I captured this photo last Sunday of a fly on a rose petal, I immediately thought "A fly is a fly is a fly."
Not to an entomologist.
The common house fly (Musca domestica Linnaeus) commonly breeds in manure, compost piles and dumpsters.
The housefly is known to transfer at least 100 different pathogens, and carry about 6.6 million bacteria on its body at a single time, according to UC Davis forensic entomologist and fly expert Robert Kimsey. It's responsible for transmitting both parasitic and bacterial pathogens as well as viruses. Among them: typhoid, cholera and dysentery (bacterial diseases) and infective hepatitis (virus).
It's enough to make you "stop and fell the roses."
