Predatory Wasps - Superfamily VESPOIDEA
and SPHECOIDEA
This page contains pictures and information about Predatory Wasps that we found in the
Brisbane area, Queensland, Australia.
Wasps have a small head, with medium sized eyes and medium length antennae. The body is slender, with a narrow waist.
They have two pairs of brown-tinted wings, with the forewings larger. The abdomen has some
yellow bands on black. Adult wasps generally feed on nectar so they pollinate
flowers as well. The ovipositors in most wasps
are modified into stingers. They will sting if disturbed.
Wasp larvae are carnivorous. They feed on
other insects and spiders. The adult female provide food for them by capturing prey or
by laying the egg on or near the food source. Female wasps spend most of their
time in finding food and making nest for their young.
Most wasp species are solitary, but some of them, such as
the paper wasps, form colonies.
Although we call this two Superfamilies as Predatory Wasps, some of them are
parasitic. Ants are in Superfamily VESPOIDEA.
Superfamily VESPOIDEA
- FAMILY
POMPILIDAE - Spider Wasps
- Most member in this family are large wasps. They are solitary insect.
Most of them are orange and black, the very strong warning colour. They hunt
for spider as prey, which they grasp and sting.
-
- FAMILY TIPHIIDAE - Flower Wasps
- Species in this family are parasitic wasps which there larvae parasite on
soil insects such as burrowing beetles larvae and mole crickets. The female
Flower Wasps has to burrow through the soil to find the host and lay an egg on
it. The female legs are modified for digging and her wings are lost.
-
- FAMILY SCOLIIDAE - Flower Wasps
- Most member in this family are large wasps. They are solitary insect.
-
-
-
- FAMILY VESPIDAE - Paper Wasps, Potter
Wasps
- Paper Wasps make their nests by chewing decayed wood mixing with their
saliva. A number of hexagonal shape cup cell grouped together to form a comb.
An egg is lay in each cell. The larvae develops and pupate inside the cell,
emerges and become an adult.
-
- FAMILY FORMICIDAE
- Ants
- All ants are in family Formicidae and all of them have waist. Their waist
is composed of one or two knobs which are the first one or two segment of
their abdomen. Their antennae have a distinct elbow. Ants live in colonies
made up of several castes. They included the winged male, winged female and
wingless workers.
Superfamily SPHECOIDEA
- FAMILY SPHECIDAE - Mud-Dauber, Sand Wasps
- Species in this family are solitary hunting wasps. Female wasp make
nest in soil or build mud cells for her young. She paralyses host
arthropod, usually caterpillars or spiders, by her sting. The sting is a
modified ovipositor which injects venom paralyses but not kill the host.
-
- There are some other wasps that we cannot identify and listed in this
page.
