Praying Mantids will usually live from spring to fall. The longest a Mantis will live is around 1 year. One of the strangest things about this insect is that the female will often eat the male and siblings will often eat each other.
Lifespan. Praying Mantids start out life in an ootheca egg mass. Usually laid in the fall on a small branch or twig, the egg mass then hatches in the spring to early summer as warming temperatures signal the time for birth. The natural lifespan of a praying mantis in the wild is about 10 - 12 months, but some mantids kept in captivity have been sustained for 14 months. In colder areas, female mantids will die during the winter. Males tend to suddenly die about 2 to 3 weeks after mating in the fall, This is usually caused by the female's urge to kill off the male once the egg pouch has been produced. (U.S. Mantids).
