Many have cryptic colouration and structural modifications that help them blend in with their surroundings. They also tend to spend a lot of their time motionless with their forelegs outstretched awaiting prey. They have good vision and their head often turns to face moving objects.
They are weak fliers usually flying in short bursts. They are predators, eating mostly insects but have been known to eat small vertebrates. They are active during the day and night. What looks similar? Mantis Flies are often confused with praying mantids as they also have raptorial forelegs. Mantid flies can be distinguished by their wings, which unlike mantids, are always present. The wings of mantis flies are clear, held tent-like over their body at rest , and possess forked veins along the wing margin.

The camouflage makes it easy for a mantis to hunt its prey. The typical lifespan of a praying mantis is six months, which can extend to a year. This stage occurs just before winter. The adult female praying mantis lays to eggs after fertilization. The eggs are laid safely on a firm leaf or stem with a liquid that hardens to be a protective sac structure known as ootheca. The ootheca is a protective casing very hard and able to survive extreme weather changes in which the eggs will stay throughout the winter.
In mid-spring when the temperatures are warm, the nymphs will hatch when the egg cases crack. Initially, the hatched nymphs stay around the egg casing for a while. It's during this period that the mantis try to feed on each other. It is advisable to use a large cage for the mating and feeding them well beforehand is essential otherwise the female will eat the male. Mating may occur immediately or it may take the male a day or so to make his approach.
Mating may last a day or more so it is a good idea to keep the cage supplied with food so the female can eat while mating. The male should be removed as soon as mating has finished. The eggs are produced in an eggcase called an ootheca this may produce 30 to young mantids depending on the species. The ootheca is a frothy mass created by the female, the froth hardens to form a tough case for the eggs. Hatching usually takes between 3 and 6 months.
The young may hatch all at once or in batches over a period of several weeks. The ootheca should be suspended at least 5cm above the floor of the cage. When the young hatch they hang by a thread from the ootheca until their skin hardens off. The female will eat a lot and become very fat before laying an ootheca on a branch or side of the container if she is already fat she may well lay her first ootheca the day after mating. She will lay several oothecae, usually about six, but only needs to be mated once.
The young nymphs can be housed together for a time but the cage must be very large with plenty of hiding places and an excess of live food must be provided to prevent cannibalism. The mantids should be housed separately after the second or third moult.
If you live in a location where mantids occur naturally you may find mantis oothecas see the photograph on our Mantodea page in the wild.
