Metallyticus splendidus
A primitive Southeast Asian mantis with metallic iridescence. Females are golden green and males blue-violet; it runs under bark like a cockroach to hunt. Rarely cannibalistic, but specific food and habitat needs make it hard to keep.
The metallic mantis (Metallyticus splendidus) is a member of the family Metallyticidae found in tropical forests of Southeast Asia such as Malaysia and Indonesia. With a short prothorax, flattened body and metallic sheen it belongs to a primitive lineage sometimes called a living fossil. The sexes differ in colour: females are golden green tinged with red, males a glossy blue-violet. It hides under the bark of dead trees and, instead of ambushing, darts after prey, mainly cockroaches, termites and flies, running on all six legs like a cockroach. Mating is unusual, the male joining abdomen tips without mounting the female, and oothecae are laid in bark crevices and hatch in 80-90 days at room temperature. Aggression between individuals is very low so groups can be kept, but its specific food and habitat needs make it a difficult species.

Keep 25-30C by day and room temperature at night. Hold humidity at 60-70% by day and 70-90% at night while ensuring ventilation to avoid stale air.
Oothecae are laid in bark crevices and holes and hold 20-30 eggs, hatching in 80-90 days at room temperature. Males mature after about seven moults, females after about eight.
Aggression toward conspecifics is very low and it is regarded as non-cannibalistic. Groups can be kept together if plenty of bark and hiding places are provided.
Males reach adulthood after about seven moults and females after about eight.
It needs running prey (firebrats, small roaches, flies); give young firebrats or small fruit flies to nymphs. Extremely fast and quick to slip into crevices, so guard against escapes when opening the cage.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Metallic Mantis is Adults 6 months to 1 year. With proper care and nutrition, they can live a long and healthy life.
