Insects:
The
Wet-Tropics Rainforests harbour approx around 40,000
species of insects!
Common
insects found are: Stick insects, moths, butterflies,
beetles, grasshoppers, ants, crickets, cicadas, ants, roaches
and fireflies. All these insects have many relatives, so you
will find a multitude of different types of the same insect in
the rainforest.
Harmful
little creatures:
-
Paralysis
Ticks: (family.
Arachnids)
- The
Australian paralysis tick (Ixodes holocyus) is found on
most of the east coast. It secretes a neurotoxin
in its saliva that causes a progressive, and
occasionally fatal, paralysis. Sometimes a severe
hypersensitivity reaction may occur. The tick will often
go unnoticed until weakness or ataxia develop, and then
is found during an ensuing search of the body. Behind
the ears and under armpits is a good place to start
looking. Occasionally localized paralysis of facial
muscles occur, but more commonly there is progressive
ascending flaccid paralysis affecting the lower limbs
first.

- Red
back spider
- The adult female red back
is about 2-3 cm long, quite black, with a distinctive red
stripe on its abdomen. Found through out Australia, the
male is much smaller and considered harmless. Neither are
aggressive. A special feature seen only with Red-back
bites is that the bitten limb may sweat profusely while
the rest of the skin remains dry. Although the toxin
is slow to act, it is important to seek medical attention
ASAP.
