Ecology, Habitat & Location

Ecological Notes Very rare and seldom seen, requiring a humid environment near the forest floor in rain forest. Slow reproduction rates meant that these insects are very sensitive to forest disturbance and habitat destruction.
Habitats Forest, Freshwater Swamp Forest, Terrestrial
Distribution Throughout South Peninsular Malaysia and Singapore. A specimen was recently found in Mandai by Kelvin Lim of the Raffles Museum of Biodiversity Research. This locally endangered species is restricted to areas of forest which frequently experience flooding.
Nature Reserves Central Catchment Nature Reserve

Conservation

Trends & Threats Habitat and food plant destruction are the most important threats. Monkeys seldom take the larger insects as their spines are protective. Monkeys however have been observed to learn how to take them by a trial and error method.
Conservation Notes The most useful conservation measure available for these insects is to increase public awareness about them. As they are very seldom seen in the wild, this may be possible only through insect observatories and cultures.
