Rep. 23. Female beetles usually lay dozens or hundreds of eggs. Physicists call these structures photonic crystals, an example of so-called “photonic band gap materials,” meaning they block out certain frequencies of light and let through others. I originally thought that this insect I photographed near Nha Trang was another beetle, but it's actually a "true bug", in particular a jewel bug called Calliphara nobilis.

The colours of jewel beetles (here, Chrysochroa sp.) Jewel beetles The shiny, beautiful jewel beetles are also known as metallic wood-boring beetles. The iridescence common to these beetles is not due to pigments in the exoskeleton, but instead is caused by structural coloration, in which microscopic texture in their cuticle selectively reflects specific frequencies of light in particular directions. They're referred to as flat-head borers because they are typically flattened, especially in the thoracic region. JEWEL BEETLES The shiny, beautiful jewel beetles are also known as metallic wood-boring beetles. True bugs don't have biting mouthparts like beetles, instead they have a straw-like tube called a rostrum which they fold under their body. Jewel beetles are often brilliantly colored, and always have some iridescence (usually on their undersides). Ten species of flatheaded borers of the family Buprestidae feed on spruce and fir, but hemlock is their preferred food source (Rose and Lindquist 1985). Jewel beetles could be especially vulnerable as they feast on leaves out in the open during the day when their wings glisten in the sunlight. Beetles cannot see very well, so they communicate using pheromones, sounds or vibrations. ThoughtCo uses cookies to provide you with a great user experience.

Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae) are family of beetles. If the insects were poisonous, their prismatic colours could be a signpost of danger, warning predators to leave them alone. Some species have well-developed jaws or mandibles used for catching and consuming prey. Most jewel beetles measure less than 2 centimeters in length, but some can be quite large, reaching up to 10 centimeters. Jewel beetle classification is not yet robustly established, although there appear to be five or six main lineages, which may be considered subfamilies, possibly with one or two being raised to families in their own right. Shape is generally cylindrical or elongate to ovoid, with lengths ranging from 3 to 80 mm (0.12 to 3.15 in), although most species are under 20 mm (0.79 in). Beetles come in all shapes and sizes. Australian Beetles FAMILY : Bark-gnawing Beetles Cadelle Beetle (Tenebroides mauritanicus) The adult Cadelle Beetle is a shiny black insect with an elongated flattened body. Jewel beetles are often brilliantly colored, and always have some iridescence (usually on their undersides). You can usually identify an adult jewel beetle by its characteristic shape: an elongate body, nearly oval in shape, but tapered at the hind end into a point. Some other systems define up to 14 subfamilies. When it comes to brightly-coloured species, being conspicuous is seen have two main purposes – find mates, or warn predators that they may be poisonous… Jewel beetles are among the largest families of beetles and over (but see text), Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Debbie Hadley is a science educator with 25 years of experience who has written on science topics for over a decade. Buprestinae Ridiculously bright colouration, metallic iridescence so remarkable you'd think it couldn't be real, or that somebody painted the thing.
