The last praying mantis that we owned laid several eggs. These eggs have been in an old Mason jar for quite some time. I was really unsure if they would ever hatch but.. today they did! There are about 20, if not more in the jar. I believe some of them did not make it but I'm not exactly sure what is going on in there. It's time to do some more in depth research. I just cannot get over how tiny they are. It's seriously incredible! It's certainly a little miracle of nature.
