DESKTOP 2781 - EUROPEAN WASP

Vespula germanica (European wasp, German wasp, or German yellowjacket) is a species of wasp found in much of the Northern Hemisphere, native to Europe, Northern Africa, and temperate Asia. It has spread and become well-established in many other places, including North America, South America (Argentina and Chile), Australia, and New Zealand. German wasps are part of the family Vespidae and are sometimes mistakenly referred to as paper wasps because they build grey paper nests, although strictly speaking, paper wasps are part of the subfamily Polistinae. In North America, they are also known as yellowjackets.

The European wasp is an established pest in Australia. This non-native wasp was first found in Australia in 1959 in Tasmania. By 1978 they were also known in Victoria, South Australia, New South Wales and Western Australia, and are now firmly established in the Sydney area.

European wasps are more aggressive than bees and will attack when their nests are disturbed.
Unlike bees, wasps can sting more than once, and do not die after stinging.
The sting causes a burning pain and swelling. If stings are multiple, a more severe systemic reaction may occur.
In some individuals, wasp, bee and ant stings can cause an allergic reaction (anaphylaxis), but this is relatively uncommon.

Effective treatment is available, which involves known bee/ant/wasp sting allergy sufferers carrying a special kit when outdoors. Immunotherapy or desensitisation is also available, and can reduce the severity of the allergy.
Seven deaths over a twenty-year period attributed to wasp stings have been recorded in Australia, mainly amongst known allergy sufferers who were not carrying their preventative medicine with them.
A cold pack may be used to relieve the pain of the sting.

DESKTOP 2652 - GRASSES

With Summer approaching, many of the grasses in the Parklands are flowering and setting seed. The cycle of the year is nearing completion and the great dry will spread the new generation far and wide; wind, animals and humans helping to disseminate the tiny packets of genetic information to new sites. Seeds to lie in wait for the Autumn rains, so as to sprout and start the cycle all over again.
