The predator and the prey...
Or the predator-to-bee.
Currently, honey bees are foraging on our tower of jewels, Echium wildpretii, in our family's pollinator garden in Vacaville, Calif. It's a veritable tower of bees.
They're side-stepping a little brown, carefully wrapped package: a praying mantis egg case, the ootheca. But sometimes they're stepping on it.
The "baby" mantids have not emerged yet, but soon they will. The siblings will eat one another before they turn to other prey.
The growing mantids will move from flower to flower and add the honey bee to their menu. Native bees, honey bees, butterflies...and it all begins right here--right here with the ootheca.
Everybody eats in the garden. Everybody.
The ootheca is a marvelous creation. Wikipedia tells us that ootheca is a Latinized combination of oo-, meaning "egg," from the Greek word oon (cf. Latin ovum), and theca, meaning a "cover" or "container," from the Greek theke. Ootheke is Greek for ovary.
"Oothecae are made up of structural proteins and tanning agents that cause the protein to harden around the eggs, providing protection and stability," says Wikipedia. "The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive advantage (although the fitness and lifespan also depend on other factors such as the temperature of the incubating ootheca)."
"The ootheca protects the eggs from microorganisms, parasitoids, predators, and weather; 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."
The ootheca also protects against tiptoeing bees. They are totally unaware of what's in this little brown, carefully wrapped package. Its presence is not a present.
