Day 1,292: nestling
Praying mantises are known for their aggression, but even so, the attack was a surprise to the researchers. They assumed it was a bizarre one off until, a month later, they caught a second mantis killing and feeding on a nestling crested lark.
Mantises are an order (Mantodea) of insects that contains over 2,400 species in about 460 genera in 33 families. The largest family is the Mantidae ("mantids"). Mantises are distributed worldwide in temperate and tropical habitats. They have triangular heads with bulging eyes supported on flexible necks. Their elongated bodies may or may not have wings, but all Mantodea have forelegs that are greatly enlarged and adapted for catching and gripping prey; their upright posture, while remaining stationary with forearms folded, has led to the common name praying mantis.
The crested lark was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.
