Magaloxantsa Bicolor (closed wings) from Thailand in nice frame with glass.

Megaloxantha bicolor is a species of metallic wood-boring beetles in the family Buprestidae. Megaloxantha bicolor is a huge Buprestid reaching a length of about 75 millimetres (3.0 in). The basic colour of these beetles is usually metallic green, but may be blue, reddish or blackish, with two basal and postmedian large yellow or whitish bands. The pronotal sides are usually bright orange-yellow. This species can be found from India to Viet Nam, Australia, Thailand and The Philippines. 

Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings is 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 70,000 member species, belongs to this order. They are 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 (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
