Sternocera aequisignata[1][2] is a species of jewel beetles belonging to the subfamily Julodinae. Its bright metallic green elytra are frequently used in jewellery making.
Description
[edit]Sternocera aequisignata can reach a length of about 30–50 millimetres (1.2–2.0 in). Elytra and pronotum have a beautiful metallic emerald iridescence that shows no to very weak reflectance in the near-infrared.[3] The Pronotum is densely punctured.
Distribution
[edit]This species occurs across southern Asia,[2] including India, Myanmar, Thailand to southern Vietnam.[4]
Lifecyle
[edit]The female lays eggs singly in soil at the base of the host plants. Each female is capable of laying 5–12 eggs, which take 2 months to hatch.[5] The hatched larva has five instar stages. Stages 1 to 4 remain in the soil for 3–4 months where they feed upon the roots of the adult host plants.[5] The 5th instar can be found above ground, until it returns underground again to pupate. Adult beetles have a short lifespan of 1–3 weeks, though the complete life cycle takes up to two years.[6]
Relationship to humans
[edit]As food
[edit]S. aequisignata and the similar S. ruficornis are both consumed by humans as a source of food in northern Thailand, Laos, and China.[7] This is one of the major sources of their decline in that area.[6]
In jewellery making
[edit]The bright metallic green elytra of S. aequisignata are collected and used as a material in jewellery making.[6][7]
