Subfamily
Brachyrhopalinae
Most eggs of
Brachyrhopalinae
have been oviposited in the soil or debris on the ground, although
Brachyrhopala
may oviposit on vegetation such as
Acacia
spp.
Cyrtopogon
oviposit 2 to
4
eggs that are elongate and creamy white. The eggs range in length from 1.12 to 1.42 mm and width from 0.42 to 0.56 mm. They have not been examined with a SEM.
The larval and pupal stages occur in the soil. The larval stage for
Brachyrhopala
lasts for about 155 days; whereas the pupal stage for
Brachyrhopala
and
Holopogon
lasts for 23 to 42 days.
Larvae of
Brachyrhopala
are reported to feed on the larvae of
Cerambycidae
(
Phoracantha semipunctata
(Fabricius))
.
Holopogon
larvae feed on
Coleoptera
and other insect larvae.
Some morphological information has been published on the larvae of
Cyrtopogon
and
Heteropogon
. Morphological information on the pupae has been published for
Ceraturgus
,
Cyrtopogon
,
Heteropogon
, and
Holopogon
.
