### Identification Measuring roughly 15–18mm, this striking hemipteran is a master of crimson deception. *Antilochus coquebertii* sports a vivid, saturated orange-red body that serves as a classic warning signal. The most reliable field marks are the bold black markings on its leathery forewings (hemelytra) and its entirely black antennae and legs. To distinguish it from the nearly identical Cotton Stainer (*Dysdercus*), look closely at the underside: *Antilochus* lacks the white transverse bands on the abdominal segments that define its cousins. Its head is also slightly more robust—the mark of a predator.
### Habitat & Range This species is a jewel of the Paleotropics, widely distributed across South and Southeast Asia, from the humid forests of India to the Malay Peninsula. You will typically find them in low-to-mid elevation tropical deciduous forests and edges. Keep a sharp eye on the trunks of Silk Cotton trees (*Bombax ceiba*) or among leaf litter where their prey congregates.
### Behaviour While most members of the Pyrrhocoridae family are sluggish seed-eaters, *A. coquebertii* is an agile, diurnal hunter. You’ll often spot them moving with a purposeful, jerky gait. They are frequently found in "aggregations," but don't be fooled by the social vibe—they are often simply gathering where the food is densest. During mating, you’ll see pairs joined end-to-end (opposed) for hours, a common trait in true bugs.
### Diet This bug is a specialized assassin. While its relatives feast on seeds, *A. coquebertii* is strictly carnivorous, preying almost exclusively on other pyrrhocorid bugs, particularly the Cotton Stainer. It uses its needle-like rostrum to pierce the exoskeleton of its prey, injecting lethal enzymes that liquefy the victim's insides before sucking them dry.
### Fascinating Fact The *Antilochus coquebertii* is the ultimate "wolf in sheep's clothing." It utilizes aggressive mimicry to live undetected within massive colonies of its prey. Because it looks and smells so much like a harmless Cotton Stainer, it can walk right into a group of its cousins and begin feeding on them without causing a panic!
