The Deroplatys gorochovi—commonly known as the Vietnamese Dead Leaf Mantis—is one of the insect world’s absolute finest masters of camouflage. Native to the tropical forest understories of southern Vietnam, this species looks so much like a piece of decaying foliage that it could easily be mistaken for a crumpled leaf or a woodland mushroom.
Physical Appearance & Camouflage
The most defining feature of D. gorochovi is its heavily expanded, wide pronotum (the structure just behind the head), which forms a large, flat shield.
-
Texture & Color: Their bodies are a matte, mottled blend of earthy browns, dark tans, and greys, complete with jagged edges and vein-like texturing that perfectly mimic a dead, weathered leaf.
-
Size Dimorphism: Females are much more robust and heavy-bodied, reaching an adult length of about 7.5 to 10 cm (3 to 4 inches) and developing distinct "shoulder blade" contours. Males are slighter and more delicate, growing to about 5 to 7.5 cm (2 to 3 inches), but they are highly capable flyers.
Temperament & Behavior
Unlike more aggressive mantis species that actively chase down food, D. gorochovi is a patient ambush predator. They will sit entirely motionless for hours, waiting for an unsuspecting insect to wander too close.
-
The "Play Dead" Strategy: If startled, they often go completely rigid or drop to the ground, blending right back into the leaf litter.
-
Threat Display: When heavily cornered, they will flash an impressive, dramatic defensive posture, exposing hidden colors or patterns under their wings to startle predators.
Captive Care Summary
Because they rely on specific environmental zones, they are generally considered an intermediate-level species for hobbyists.
-
Environment: They thrive in taller, arboreal enclosures with plenty of vertical surfaces like cork bark, twigs, and dried foliage to hide in and hang from securely while shedding their skin (molting).
-
Climate: They prefer a warm environment between 22°C and 28°C (75°F to 82°F) and require relatively high humidity—around 60% to 80%—which can be maintained with daily misting. Good ventilation is essential to keep the air from stagnating.
-
Diet: In captivity, they heavily prefer flying aerial prey like fruit flies as nymphs, moving up to house flies, greenbottle flies, and wax moths as they mature.
