If you don't know what it is, don't kill it.
That insect in your garden could very well be a beneficial insect.
If you operate on the "shoot-first-ask-questions later" or "the only good bug is a dead bug," no telling how many insects--and generations--you'll be destroying.
Butterfly expert Art Shapiro, professor of evolution and ecology at UC Davis, tells this story that's worth remembering.
"Last week I was walking across Capitol Park in Sacramento when I observed a smartly dressed young woman in her 20s stomp a praying mantis and grind it into the sidewalk. She exclaimed to her phenotypically similar friend: 'Did you ever see such an ugly, icky bug?'"
And, many years ago, Shapiro encountered a man in College Park, Davis, in the act of stomping a Tiger Swallowtail.
Shapiro asked him why he was doing this.
The man replied: "This is the bug that has the big green caterpillar that eats my tomato plants!"
When Shapiro told him it wasn't, the man told him to check his information, and that "I'm right and you're wrong."
There is indeed a lot of misinformation and misidentification out there.
Tabatha Yang of the Bohart Museum of Entomology at UC Davis relates the story about an avid gardener who absolutely loved ladybugs (aka lady beetles) because of their voracious appetites for aphids. But when our avid gardener came across "some weird black and orange bugs," she promptly killed them.
Little did she know that she was killing immature ladybugs.
Then there's the story about a UC Master Gardener who encountered a "green-eyed golden bumblebee-like" insect that frightened her because it buzzed so loudly around her flower beds. So, she killed it. Turns out it was a pollinator, a male Valley carpenter bee, also known as a "teddy bear."
And, can you imagine what goes through people's minds when they meet up with a Jerusalem cricket in the mud after a rain? Whoa! Bug-o-mania!
Here's where the Bohart Museum, 1124 Academic Surge on California Drive, UC Davis campus, can help. If you live in California and see an insect and wonder if it's beneficial insect or a pest--or just want to know what it is--take a photo of it and email it to the Bohart. Lynn Kimsey, director of the Bohart Museum (home of more than seven million specimens) and professor of entomology at UC Davis, identifies insects in between research, teaching, administering the Bohart Museum, and other duties. Her email address: lskimsey@ucdavis.edu.
In fact, if you go to the UC Davis Department of Entomology home page and scroll down to the bottom you'll see:
"Do you have an insect question? Ask It Here!"
Maybe, just maybe, this will save a few praying mantids, ladybugs, Valley carpenter bees and Jerusalem crickets.

Mother's Day, insect-style, dawned like any other day. In our back yard, golden honey bees foraged in the lavender and those ever-so-tiny sweat bees visited the rock purslane.
The honey bees? Those gorgeous Italians.
The sweat bees? Genus Lasioglossum, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis. He figures the female sweat bee (below) may be L. mellipes, which is brownish toward the tips of the hind legs.
A trip to Benicia yielded a photo of a ladybug chasing aphids. It was almost comical. A fat aphid appeared to be playing "King of the Hill" while other aphids sucked contentedly on plant juices, unaware of pending predators.
While the aphids wreaked havoc on a very stressed Escallonia (fast-growing hedge in the family Escalloniaceae), the ladybugs, aka lady beetles, wreaked havoc on some very stressed aphids.
After all, "stressed" spelled backwards is "desserts."

"You can never be too rich, too young, too blonde or too thin," a quote often attributed to Wallis Simpson, Duchess of Windsor.
Well, you can never have too many ladybugs, aka lady beetles, in your garden.
These colorful beetles devour aphids and other soft-bodied insects. It's a war of the predators and their prey.
Fortunately, when there are scores of aphids sucking the very lifeblood out of your plants, you're likely to see both ladybugs AND soldier beetles. Both like to dine on aphids.
Soon the ladybugs and soldier beetles do what comes naturally. (Unfortunately, so do the aphids.)
More ladybugs, please! More soldier beetles, too!

There's a good reason why lady beetles, aka ladybugs, are prevalent this time of year: aphids.
Ladybugs, from the family Coccinellidae, are actually beetles with voracious appetites for those soft-bodied insects that suck plant juices.
Wherever there are aphids, you'll usually see ladybugs. It may take awhile for the ladybugs to find them, but find them they will.

The overwintering ladybugs tucked in the leaves of our tangerine tree are gone.
Sunny temperatures hit 75 degrees, and off they went. Guess they thought it was spring.
Anyhow, they made a glorious sight as emerged from the folds of a tangerine leaf. One perched on the top of a tangerine tree and then crawled up and down the leaf.
Natalia Vandenberg, a USDA employee with the Systematic Entomology Lab, Smithsonian's National Museum of Natural History, identified these as an introduced species, Coccinella septempunctata.
Ladybugs in February...
