Aliens have started the season of battle.
I have both Tenodera sinensis
(Chinese mantid) and Stagmomantis carolina
(Carolina mantid) in my yard.
While removing brush in December, I saved a Chinese mantid ootheca and put it into protective custody in a critter keeper under a porch eave. Late yesterday, they emerged. If you enlarge the photos, you can see most through the lid slats. A couple hundred of them have now started the year's battle in beds encircling the house.
All of my Carolina mantid egg cases are against brick, wood, or other surfaces making them risky to attempt to remove and protect.
Now, I'm keeping an eye on my six Argiope aurantia
(black and yellow garden spider) egg sacs...
