South American Dead Leaf Mantis (Acanthops falcata)

Acanthops falcata

The Acanthops falcata, the South American Dead Leaf Mantis. It is the pinnacle of Neotropical cryptic camouflage: this mantis does not just imitate a dead leaf, but a crumpled and deformed leaf fallen to the ground. Adult females are inept at flying, have very short wings similar to scaly stumps and a stocky and deformed body, often kept curled up on itself (Thanatosis) to look like an inanimate vegetal waste. Males, on the contrary, are long, slender and skilled flyers (they literally fly like diurnal blowflies). Extremely static and peaceful, the falcata has a highly intolerant stomach: the diet must consist exclusively of drosophila and flying flies, ingestion of crickets leads to instantaneous bacterial digestive collapse.
