TYPICAL JEWEL BEETLES
BUPRESTIDAE: BUPRESTINAE
M
ost Buprestinae are fairly large, metallic,
bullet-shaped diurnal species that fly rapidly
in sunshine. Unlike Agrilinae, adults of several
Buprestinae genera such as the Old World Anthaxia
and the Australian Castiarina and Melobasis feed
regularly, and are often found on flowers eating
nectar and pollen. Some other genera, such as
Buprestis and Chrysobothris, are more often seen
on the wood of host trees, where they are well
camouflaged despite their shining appearance.
The antennae of all jewel beetles are short but have
powerful scent detectors, and beetles can locate
host trees from a considerable distance. Their
eyesight is also excellent, and, especially when they
are warmed by the midday sun, they are difficult to
photograph, catch, or even approach, as they take
flight at the least disturbance. Some species use
sight to detect a mate: in the large, brown Australian
Julodimorpha bakewelli, the males are attracted to
discarded beer bottles that have a dimpled pattern,
which apparently resembles a giant female beetle!
Some Buprestinae have very specific
requirements. Melanophila acuminata is completely
black, and lays its eggs in blackened pine trees that
were recently burned. They fly very high, using
special infrared sensors to detect forest fires, then
descend to oviposit in the freshly charred timber.

Larvae of most species eat wood. Adults, if
they feed at all, eat nectar and pollen or sap
and small leaves
notes
The name Buprestis, on which Buprestinae
and Buprestidae are based, means “cow
sweller” or “cow burner” in ancient Greek,
which is surprising for a harmless beetle!
