This page contains pictures and information about Wattle Tick Scale that we
found in the Brisbane area, Queensland, Australia.
-
 - Diameter 5-10mm
-
- This Scale Insects form large ball shaped 'scale'. The pictures show
ants are attending them for their honey drew. They are found on different
species of Acacia. Usually they cover the whole section of stem on
young trees.

- The
Wattle Tick Scale insects are covered with wax secretion. From their appearance they do not look like
insect at all. When they grow, most of their external organs, such as their legs, wings
and antenna, are reduced and become functionless.
-
 -
- The young scale insects have three pair of legs, known as 'crawlers'. They
spread and look for suitable place to start new colony. They are very small,
even they have no wings, they can spread by wind
borne.

- Robert Whyte sent us email advise that this brown scale on the acacia might
be Cryptes baccatus. We checked and agree with him. Check this page
for more information.
