Praying Mantis Winter NEST

Does anyone have good photos of winter nests
or advice to introducing praying mantis into my land?
I have seen them but would like to increase their population if possible. Thanks!

I almost composted a nest this year but caught it in time.   The best way to attract beneficial  insects is to create habitat.

Here is a picture link
