PHILADELPHIA, PA (WWBT) - A Facebook photo claiming to show an egg in a Christmas tree is being shared online as a warning to check your trees.
It's a "praying mantis" egg, and it turns out the photo is real.
Experts say the egg case could have more than 100 eggs inside.
As for whether or not it could hatch inside your house, experts say the eggs need warmth to survive but need several weeks to develop.
If you find an egg case like this in your tree, you should clip the branch and get it back outside, so it can hatch normally.
