I found one under my oscillating sprinkler. should I move it someplace where it will be dry or just leave it out in the yard over the winter?
That is a wonderful thing to have around. They are predatory, meaning they will eat pest bugs. The mantis will find the most suitable place naturally, and wherever it laid those is where they wanted to lay them.
You can care for them if you would like. You will need a terrarium. Replicate the outdoors with grass and sticks. Leaves help too. They will hatch, and at that time you can feed them small insects.https://www.gardeningknowhow.com/garden-how-to/beneficial/praying-mantis-egg-sac-info.htm
so you're saying I could pull it off the sprinkler and put it in a terrarium in my house?
I have some pet ladybugs, and it is almost winter where I live. I was wondering if there is anything that I should do before the ladybugs hibernate? Is there anything specific that they need for hibernation? I was also wondering when ladybugs lay their eggs?
We don't really specialize in insect care here. It should be noted that if these are intended to be predator bugs to keep insects from eating your plants then it would be best to make absolute sure that these are, in fact, ladybugs. Many hybridized lady beetles were released purposely, and unlike true ladybugs, they also feed on plants as well as small insects.
To find out more care on these insects, you can ask your local extension service, which you can find by using this link: https://www.gardeningknowhow.com/extension-search/
