There was an unexpected guest welcoming me home a couple of days ago. He was resting on the inside of the window frame. He must have sneaked in through the open door, as all the windows have bug screens.
Praying Mantis, a very strange insect indeed. They have triangular heads with bulging compound eyes, three smaller eyes and a pair of antenna supported on flexible necks. They can see in 3D with all those eyes. They can turn their heads almost 180 degrees. Their front legs are enlarged and adapted for catching and gripping prey.
A PM this size would go for insects, but they are capable of killing prey 3 times their size. The larger varieties have been known to eat humming birds, frogs and lizards. They like their food sill squirming!
