Tooth and Claw: Praying Mantises

Investigating an insect known for eating its prey alive – including, at times, its own species - the praying mantis! With bulging eyes and a triangular head, this predator uses it specially adapted front legs to trap its prey.

Able to predate animals of a size much larger than themselves, including birds, lizards and even fish, presenter Adam Hart hears about their cultural significance to human populations all around the world, as well as addressing their reputation for sexual cannibalism. We also hear about their biomaterial qualities and potential importance in agriculture, and also look into a parasitic relationship the praying mantis has with a worm in South America which has given them the name ‘the mother of snakes’.
