Mantophasma zephyra
Tyrannophasma gladiator
Namibophasma ookiepensis

Conservation

Generally not considered endangered. However, their specific habitats may be vulnerable to environmental changes.

Significance to Humans

Primarily of interest to entomologists and biologists studying insect evolution and taxonomy. No direct economic significance.

Fun Facts

First discovered in 2002, making them one of the most recent additions to the insect order.
Named "heelwalkers" due to their unique walking style.
They lack wings entirely in both sexes, a rare trait among insects.
The order Mantophasmatodea was initially placed within the order Notoptera, with an evolutionary link to both mantises and stick insects.
