Well camoflaged in a Black Wattle (Acacia leiocalyx), is the arboreal and diurnal Green Tree Snake living along the riparian zone on Sportsman Creek wildlife refuge.

An adult Tree Goanna of 2 metres in length displaying perfect camoflage in the riparian zone on Sportsman Creek wildlife refuge today.” Very capable hunters of birds, mammals and any other reptile of suitable dimension and will also feed on carrion and eggs.”

Photographed today on the wildlife refuge. These moths have “eye spots and teeth pattern on the upper wing surface which resemble a big mouth predator. Their abdomen is bright orange and bottom of their wings are brownish yellow. In the air they resemble a bright orange flying insect”.

The caterpillars move by curling their bodies into a loop, hence the name Looper Moth. They have camoflaged wing patterns and at rest tightly press against the surface to eliminate shadows for better camoflage. They are not strong fliers and are reasonably common on the wildlife refuge.

Adult winged grasshopper in full camoflage mode which it uses to hide in dry gum leaves. When disturbed will fly a few metres and fall into more leaves. Image taken mid-January.

Also called Walking-stick insects. Phasmids are herbivorous feeding on leaves of trees. The abundant Soft-fruited Teatree (Leptospermum brachyandrum) is the favoured food source across the wildlife refuge. Females are the largest insects in the world up to 13″ in length and are considerably larger than males. They also lay up to 1000 eggs and are an important food source for many species of birds.

The foamy egg case or (Ootheca) of the Australian Garden Mantis. These remarkable, beneficial insects are a general ambush predator of most insects, mites and aphids. The Ootheca is usually placed in the crotch of a tree from which up to 200 baby mantids will emerge. Commonly found across the wildlife refuge.

Note; Preying mantis eggs are available to purchase over the web and are a must in any garden or horticultural activity.

These butterflies can be found out and about at dusk at Sportsman Creek wildlife refuge. They hide amongst the dead leaves with wings folded, when disturbed fly a short distance and fall in with the vegetation in perfect camoflage.

Resembling dried leaves is perfect night camoflage for this Threatened Species of Green-thighed frog. Conservation actions include protecting the natural actions of local flooding and maintaining vegetation and leaf litter around ponds, dams, drainage lines and other moist areas.
