### Identification The *Oxypilus hamatus* is a miniature marvel of camouflage, usually measuring a modest 20–30mm. At first glance, you might mistake this mantis for a scrap of lichen or a bit of gnarled bark. Its body is a mottled tapestry of earthy browns, silty greys, and charcoal blacks. The defining field mark is the "hooked" appearance of its head—the specific epithet *hamatus* refers to these hook-like projections. Look closely for the distinct, conical processes atop its compound eyes, giving it a tiny, "horned" silhouette. Unlike the sleek, leaf-mimicking mantids of the tropics, this species is rugged and textured, with heavily spined raptorial forelegs designed for a vice-like grip on slippery prey.
### Habitat & Range Primarily a resident of West Africa—with frequent sightings in Gambia, Senegal, and Ghana—this species thrives in savanna-woodland mosaics and dry scrublands. You will typically find them at lower elevations, perfectly positioned on the textured trunks of acacia trees or tucked within the twiggy recesses of sun-bleached shrubs where their cryptic coloration blends seamlessly with the peeling bark.
### Behaviour In the field, you’ll notice their incredible stillness. They are diurnal ambush hunters that rely on "crypsis" (blending in) rather than speed. When they do move, they often employ a rhythmic, jerky "rocking" gait. This isn't a lack of coordination; they are mimicking a piece of dried leaf or debris caught in a light breeze to avoid the sharp eyes of insectivorous birds.
### Diet These are opportunistic generalists. They lie in wait for small dipterans (flies), micro-moths, and other small invertebrates. When an insect wanders within range, the *O. hamatus* strikes with a lightning-fast extension of its forelegs, pinning the prey between its tibial spines in a fraction of a second.
### Fascinating Fact Despite their tiny size, they are masters of psychological warfare. If a predator gets too close, they perform a "deimatic display," suddenly flaring their forelegs to reveal hidden, high-contrast markings that startle the attacker just long enough for the mantis to drop into the leaf litter and vanish!
