Order Hemiptera
- This page contains pictures and information about Lygaeid Bugs in Superfamily LYGAEOIDEA
that we found in the Brisbane area, Queensland, Australia.
-
-
- Bugs in superfamily LYGAEOIDEA may look very similar to those in COREOIDEA.
They can be distinguished from the Coreid Bugs by their forewings which have
less dense longitudinal parallel veins. There are at most five of
those veins.
-
- Lygaeid Bugs are mostly in bright red or yellow in colours, with some
are black or brown. They have elongated body. Ocelli present. Scutellum with
distinct and weakly raised Y-shaped mark. On fore-wing membrane usually has 4-5 longitudinal veins.
-
-
-
- Most of the Lygaeid bugs feed on seeds or plant sap. In the breeding
season adults and different stage instars can be found feeding on the same
 Family
Rhyparochromidae - Seed Bugs- Seeds Bugs in Rhyparochromidae are small is
size and dull in colour. They are either brown or mottled with dark and pale
patterns. The head is usually large and triangular with ocelli. Antennae are
four segmented. They usually have strong front legs. Most of them feed on ripe
seeds that dropped on ground. Fightlessness is common in this
family.
-
 Family Lygaeidae - Seed Bugs, Milkweed Bugs, Chinch Bugs- Members
in his family have their forewings with 4-5 veins. The front section of their forewings is
slightly harden and the back section membranous. They are
usually brown to red in colour. They are from 4 to 20mm long, with oval shape and flattened
body. Their antennae are four segmented.
-
 Family
Geocoridae - Big-eyed Bugs - Bugs in this group have very big eyes and they are commonly called
Big-eyed Bugs. They have either elongate, elongate-ovoid or oval body. They
are seed feeders but also known to be predaceous. This geocorids were put as
the subfamily of the Lygaeidae. They are raised to family level in 1997.
-
 Family
Oxycarenidae - Coon Bugs- We found one species in this family. The bugs are small in size. Their
back is triangular-patterned in black and white colours. We found them on
our hibiscus plants on early spring. The nymphs are black in colour with
blood-red abdomens.

 Family
Pachygronthidae - Pachy Bugs- This is a small insect family in Australia. There is not much information
about them. The bugs have the slender and elongated body usually pale brown in
colour. The antenna are very long. The front pair of legs are enlarged and armed with prominent spines.
