If you've been pruning bushes or trees, check to see if a praying mantis egg case (ootheca) is attached to a limb.
If you do, you're in luck!
A mantis deposits her egg case in late summer or fall, and usually on twigs, stems, a wooden stake or fence slat, but sometimes even on a clothespin.
The nymphs emerge in early spring.
The hard egg capsule protects the future offspring from "microorganisms, parasitoids, predators, and weather," Wikipedia tells us. The ootheca "maintains a stable water balance through variation in its surface, as it is porous in dry climates to protect against desiccation, and smooth in wet climates to protect against oversaturation. Its composition and appearance vary depending on species and environment."
Meanwhile we've been watching a neighbor's gift: an ootheca attached to redbud twig. With any luck, we expect the nymphs to emerge around April 9, weather permitting.
Back in 2022--April 9th to be exact--we were delighted to see some 150 nymphs emerge from the clothespin just a'hanging on the line. Of course, the sisters and brothers ate one another. Only a handful survived.
It's survival of the fittest. Or the fleetist. Or maybe just luck?

Today is Black Friday, a day that marks the beginning of the Christmas shopping season. It's reportedly the busiest shopping day of the year.
But to us, today is Green Friday, in recognition of a female green praying mantis,Stagmomantis limbata.occupying a rib of a tall green cactus in our Vacaville garden. This is not her "busiest shopping day" of the year.
Ms. Mantis is not praying or preying. She is resting. She is clinging to a Pachycereus marginatus, also known as a "Mexican fence post."
She's the last of the season. She's already deposited her egg case, an ootheca, and she's about to expire.
Ms. Mantis peers at me with her super-duper 3-D vision. She can turn her triangular-shaped head 180 degrees. She's an ambush predator and a strikingly fast predator at that. She can nail a bee, fly or butterfly with her spiked forelegs in about 50 to 70 milliseconds.
But not now.
She is resting. She is the last of the season.
It's Green Friday.

Last fall, a Stagmomantis limbata deposited her egg case, or ootheca, on a clothespin on our outdoor clothesline. On April 9, the clothespin sprang to life. Hundreds of nymphs emerged, scrambled away, and vanished.
Some wandered around on the clothesline. Some ate one another. Some survived to adulthood.
We saw only four in our pollinator garden: a female in the patch of lion's tail, Leonotis leonurus; a female on the Mexican sunflower Tithonia rotundifola; and a male and female in the African blue basil, Ocimum kilimandscharicum × basilicum 'Dark Opal."
They appeared, disappeared, and never re-appeared.
Meanwhile, our lantana, Lantana camara, proved to be a magnet for such pollinators as honey bees, syrphid flies, skippers and cabbage white butterflies, but nary a praying mantis.
Fast forward to the late afternoon of Sept. 25. There perched in the flood of red and gold blossoms was a gush of green, a beautiful gravid praying mantis, S. limbata, looking as if she'd never missed a meal and looking quite Mama-like.
How did we ever miss her?

Talk about a quail of a time....
When the ootheca of a praying mantis, Stagmomantis limbata, hatched April 9 on a clothespin clamped to our clothesline in our yard, all the nymphs scattered. Some crawled up a metallic quail sculpture, the highest structure on the clothesline. (See Bug Squad blog)
A bird's eye view? They scrambled about, covering the beak (beak-a-boo), the eyes and the tail (bright-eyed and bushy tailed), and the wings (were they just winging it?).
If a flock of quail is collectively known as a flock, covey or bevy, what is the collective noun for a group of mantids?
A mass of mantids? A pack of predators? A prayer meeting? Or a prey-er meeting? Brothers and sisters, we are gathered here today....let us prey.
Only a few will survive to maturity. Many have already been eaten by a brother or sister. And some will lose their head to a female suitor (sexual cannibalism).
Birds of a feather may flock together, but praying mantids do not. They keep their compound eyes on the prize, and spiked forelegs on their prey.
None would ever be nominated for Miss or Mr. Congeniality.

Saturday, April 9 was the day a clothespin sprang to life.
Some 200 praying mantis nymphs emerged from an ootheca that Mama Mantis (Stagmomantis limbata) had deposited last summer in our pollinator garden in Vacaville.
We first noticed the camouflaged ootheca (aka eggcase or ooth) on the wooden clothespin in mid-March when we were hanging a freshly laundered dog blanket on the line.
Then on that warm Saturday, with temperatures edging 80 degrees, the clothespin exploded with life. From a distance, the nymphs looked like feathery little ants flicking about.
Mama's babies.
Looking a lot like Mama, they edged out of the ooth, crawled up and down the clothesline, and then some ascended a metallic quail sculpture, the highest point.
A bird's eye view.
Praying mantis experts say that only a handful will survive to maturity. Yes, they will eat one another, along with other small insects such as fruit flies and aphids. Then they will advance to larger prey.
When Sunday dawned, they were gone.
Mama's babies.
