I have been observing mantis eggs outdoors for a long time.
But as the weather got warmer, I found a strange mantis egg.
A mantis egg with a large hole in it...
And from that hole came an unknown bug.
A parasitic worm that lays eggs by inserting a ovipositor into the mantis egg and eats the mantis egg!
It is the carpet beetleAnthrenus nipponensis),
Today we are going to learn about these insects.
