Praying Mantis Ootheca(egg sack)
Tenodera Aridifolia Sinensis (Chinese Mantis)
Praying Mantis feed on aphids, beetles, caterpillars, chinch bugs, Colorado potato beetles,
leafhoppers, hornworms, leafrollers, squash bugs, thrips and whiteflies. They start off feeding on
fruit flies and other tiny insects and as they grow so does their prey.
Outdoors, egg cases hatch in mid-June when the weather is hot enough and the daylight hours are longer. Inside, they take
anywhere from two to eight weeks to hatch. Egg cases be attached to a plant about a foot or two off
the ground. Once hatching commences, all praying mantis will hatch within about one hour. When
hatching, the young crawl from between tiny flaps in the cases and hang from silken threads about
2″ below the case. After drying out, the long-legged young disperse quickly into the vegetation as
they are cannibalistic.
It’s very difficult to know hatching has occurred unless the elusive, well
camouflaged young are found. (The egg case does not change appearance in any way).
Each mantis will set up its own territory where it will live for the summer. If you’d like to see when
the mantis have hatched, place the egg cases in a paper bag, fold the top and seal shut with a paper
clip or clothes pin. Place the bag on a window sill in direct sunlight. Periodically open the bag
carefully, and when you see tiny mantids running around inside, take them outside and sprinkle
them throughout the garden or release them into a terrarium.
INSTRUCTIONS FOR HATCHING INDOORS
