Meet the world's largest tiger beetle: Manticora

In the dry savannahs and rocky outcrops of southern Africa, something large moves at night. Manticora — the largest tiger beetle in the world — reaches 65 mm in body length, with mandibles disproportionate even by Cicindelidae standards. It is wholly flightless, entirely nocturnal, and named after a mythological monster.

Why so large?

Body size in predatory beetles correlates with prey size. Manticora takes prey considerably larger than itself — other beetles, orthoptera, small scorpions have been recorded. The mandibles, proportionally the most massive in the family, can sever the cuticle of other large arthropods. This is a top predator in the savannah invertebrate food web, not a pursuer of small flies.

Flightlessness in Manticora is complete — the hindwings are vestigial and the elytra are fused. This is correlated with large body size across multiple Cicindelidae lineages: Amblycheila in North America, Omus in the Pacific Northwest, Apteroessa and Apterodela in Africa. Large body mass makes flight energetically expensive; in stable, predictable habitats, the metabolic cost outweighs the dispersal benefit.

13 species, one genus

The Cicindelidae matrix records 17 Manticora species and subspecies, all restricted to the Afrotropical region. All share the same basic body plan: matte black (no metallic lustre), robust, heavily sclerotised, with small compound eyes reflecting their nocturnal lifestyle. Eye size in Manticora is proportionally the smallest in tribe Manticorini — the large eyes that define most Cicindelidae are a liability in darkness.

The name

Fabricius named the genus in 1792 after the mantichóras — a creature described by the Persian physician Ctesias around 400 BC: man's face, lion's body, scorpion's tail, devouring all prey it encounters. The allusion is explicit and well-chosen. A Manticora encountered at night on an African game trail is, at 65 mm with open mandibles, genuinely alarming.
