Thylactus angularis is a species of beetle in the family Cerambycidae. It was described by Francis Polkinghorne Pascoe in 1866. It is known from Sumatra and Malaysia. [1]
Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 80,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
Francis Polkinghorne Pascoe was an English entomologist mainly interested in Coleoptera, commonly known as beetles.
Sumatra is a large island in western Indonesia that is part of the Sunda Islands. It is the largest island that is located entirely in Indonesia and the sixth-largest island in the world at 473,481 km2.
