Be on the lookout…there may be treasure in your garden.
During your spring cleanup, you will no doubt uncover all kinds of delightful signs of life: the healthy shoots of perennials, dozens of tiny seedlings or wiggly earthworms under fallen leaves. One treasure you should be on the lookout for, and not mistake as something bad is the over wintering egg case of Praying Mantes (or Mantids). These pale tan Styrofoam looking sacs are attached in the crotches and on the undersides of bare branches. In late spring they will begin to split, upon which a hundred or more tiny translucent Praying Mantes will unfurl and march away to devour a wide variety of your most irritating garden pests. We were absolutely delighted to learn that they voraciously eat grasshoppers, which are a nuisance we’ve had difficulty with in the past.
The Praying Mantis is a most fascinating insect to observe in the garden. They sit motionless in the garden waiting for their prey to pass by. And yes, it is true that the females practice sexual cannibalism, (but not always, we’re told). Often the male is just not thinking straight when he has copulation on his mind and surprises the female as she sits motionless. Her first reaction is to grab hold and bite off his head (she needs the extra protein for pregnancy!). The male is able to fulfill his mission nonetheless and we hear he dies happily ever after.
