This page contains pictures and information about Predatory Stink
Bugs that we found in
the Brisbane area, Queensland, Australia.
- Predator and prey
- Most of the stink bug species are
plant suckers, however stink bugs in subfamily Asopinae are predators. Both adult and
nymphs (except 1st instars) prey on other slow moving soft-skinned insects,
such as caterpillars and beetle larvae. Their rostrum (the
mouth parts) is directed away from the head and the first segment is robust
and thick. This is an adaptation to their predatory habit.
- Those Predatory Stink Bugs are sometimes found feeding on caterpillars. If disturbed, they
seldom abandons their prey but slowly walks away carrying the meal with them.
- We found three species of
predatory stink bugs and listed as follow.
- Glossy Shield Bug, Predatory Shield Bug
- Cermatulus nasalis, 1st
adult, body length 20mm
- This is a Predatory Stink Bug. Although most stink
bugs are plant feeders, this
predator on soft-body insects, including caterpillars. Their eggs are laid in
group of 50 or more which are
black in colour with short white spines around the rim. Young instars are
bright red in colour. Later instars are dark red and brown. More information
and pictures please click here.
- Yellow Predatory Shield bug
- Amyotea hamata, body length 12mm
- The bug is orange-yellow, with black marks on the upper and
lower surfaces of the body. We took those pictures after the bug flied and landed on the
Lantana leaf in Wishart. This bug is a predatory bug. Please check this page
for more information.
- Spined Predatory Shield Bug
- Oechalia schellenbergii, adult body length 15mm
- The Spined Predatory Shield Bug is mottled brown in colour. It is easily recognised by the
sharp spines on either side of the shoulder. The above picture shows the bug feeding with piercing-sucking mouthparts on
beetle larvae. More information and pictures please click on here.
