Also called the Pretty face Wallaby. The most beautiful and boldly marked of the mid-sized kangaroos. The Whiptail gets its name from its long tail that tapers to a whip-like end. Discontinuous populations from Cooktown south to the north-eastern New South Wales border from coastal areas to the western edge of the Great Dividing Range. Image taken in the foothills under the Great Divide amongst some old growth forest.
Powerful Owls are frequent visitors to the Conservation Area where they hunt along the riparian zone for Gliders, Possums and Bats. It was suggested by the photographer that the Powerful Owl may have the ability to branch hang using a bony protrusion on the wing. After sending the images to the Australian Museum this has now proved to be incorrect.
Your great images were shown to Walter Boles, Senior Fellow in our Ornithology Section. His response was:-
” Yes, it is definitely a Powerful owl, Ninox strenua. I have handled lots of unprepared carcasses of this beast–possibly more than anyone else in the world–and have never found anything on the wing that could be construed as a branch-hanging bony protrusion. To me, it looks like a bird that grabbed a possum and slipped, getting its wing caught in the fork. Just to check, I forwarded the pictures to two of Australia’s leading owl workers and both have the same conclusion. So, no confirmation of a bony protrusion. Just a clumsy owl.”

Also known as the Hibiscus Harlequin Bug the image on left is of an adult male with metallic blue and red patches. The image on right is a fifth instar Nymph with bright metallic blue colour. They feed mostly on young shoots piercing and sucking the stems of Malvaceae. Not commonly found in the Conservation Area after hitching a ride in a visiting vehicle.
With no common name this attractive fungi is common on lawns and playing fields where it sometimes forms large fairy rings. The lilac tints are rapidly lost as the fruiting bodies dries. Cap 3-8cm with a strong pleasant smell. A new species for the Conservation Area.
Known for the violin shaped pattern on their backs these attractive and common beetles live in heaths and woodlands. The female Fiddler Beetle lay their eggs in rotting timber or in damp soil under logs. The grubs feed on rotting timber and build cocoons of soil and debris in which they pupate. These beetles are harmless to humans.
We are pleased to have reached a significant milestone in our ongoing commitment to the identification, study, research and sharing of species information through the Sportsmans Creek Conservation Area in the Clarence Valley of Northern New South Wales. Our environmental commitment to this property began as a personal pathway but it soon became obvious that the information we were gaining deserved to be more widely distributed. A solar powered laptop and the medium of blogging has allowed us to achieve a much wider audience for the 650 identified species of flora and fauna found to date. As of today over one hundred thousand people have visited the web page to learn and research from all around the world including the Natural History Museum of London.
“The boletes are closely related to the agarics (fungi with gills). Many boletes display colour changes when the flesh is cut, so that whitish or yellowish tissues become spectacularly greenish blue due to enzyme reactions triggered by oxygen in the air. Boletes are very important in the Australian bushland as ectomycorrhizal species, but they also provide food for the larval stages of many insects.” A first time sighting in the Conservation Area after recent rains.

With over fifteen hundred recorded species across Australia and S/E Asia and twenty thousand species worldwide these common beetles are scavengers and feed on both fresh and decaying vegetation. Major predators include birds, rodents, sunspiders and lizards making them an important link within the food chain.

Belonging to the ground beetle family (Carabidae) with over two thousand five hundred species Australia wide these beetles are carnivorous and hunt on the ground or in trees. Their larvae feed on other insects. When threatened the Bombardier Beetle uses a special gland at its rear to mix together two chemicals, resulting in an explosion with a loud popping noise and an accompanying sizzle of spray and steam with temperatures over 100 degrees Celsius in the gland. Up to 80 explosions may be produced over a four minute period.

To the east of Sportsman Creek Conservation Area lies the Yuraygir National Park being the last refuge for the Coastal Emu now numbering less than 100 individuals. Once in abundance the local population has been in steady decline over the past twenty years as a result of habitat loss, fires during breeding season, predation by foxes and wild dogs and collisions with vehicles. Populations of the Coastal Emu which are isolated from their inland relatives now only exist between Evans Head and south to Red Rock. Yuraygir National Park south of the Clarence River is home to one of three distinct sub-populations in this region. The Coastal Emu has recently been listed as an Endangered Population and has disappeared from Red Rock and Iluka.

“Of five known species in this genus at present, all of them restricted to Eastern Australia. This species is usually found in wet forested situations like Antarctic Beech forest, wet sclerophyll forest and rainforest.” Recent floods have expanded the breeding territory for this large frog and was discovered in a dam under Open Eucalypt woodland on the Conservation Area.
M. fasciolatus has a deep, harsh “wark” call and can grow to 90 mm. The tadpole in the image measured 110 mm.

Water Scorpion grow to over 50mm long they can extend the tube on their backs out of the water to breathe air like a snorkel while swimming. They can ambush fast swimming prey such as small fish catching them between their front legs and stabbing them with their pointed probiscus. Known as Toe-biters able to inflict a nasty nip although this specimen played dead when disturbed. Water Scorpions are also capable fliers and inhabit waterholes over much of Australia.
” A beetle not a bug. It is certainly one of the diving beetles in the family Dytigcidae, but there are a few black and yellow genera and species. This beetle could be in the genera Megaporus or Sternopriscus.” Found in the dam feeding on small aquatic organisms.
“Also known as Verreaux’s Burrowing Skink or the Three Clawed Worm Skink. The best diagnostic feature for this lizard is the pale collar, clearly visible on this specimen, which helps distinguish it from (Coeranoscincus reticulatus) the Three-toed Snake-tooth Skink.” These lizards live in loose soil, leaf litter and rotting logs feeding on earthworms and beetles. Because of its burrowing habits it is seldom seen and a new species for the Conservation Area.

“Although widespread and found in a variety of habitats, particularly around temporary swamps this frog is not common. Also known as the Freycinet Frog they reach 45mm and are similar to Litoria nasuta, from which it can be distinguished by the thigh pattern of brown and cream spots.” A new species for the Conservation Area and named after L. Freycinet, the French Navigator. They are capable of very long leaps.
“Adult moth has brown forewings with a dark green sheen, and with a sharply defined broad white border along the edges of the wings. The hindwings are orange, with a black border and black comma in the middle. The moth has a wingspan of about 8cm.” A new sighting for the Conservation Area with the common name Green Fruit-piercing Moth.

The peer-reviewed quarterly journal Systematics and Biodiversity recently published the report – Perspectives. Colour and size variation in Junonia villida ( Lepidoptera, Nymphalidae ) : subspecies or phenotypic plasticity ? by R.I. Vane-Wright and W. John Tennant.
The review was based on” examination of c.1500 museum specimens from its entire geographical range from the Chagos Islands in the Indian Ocean to the Gambiers in mid-Pacific, spanning over 154 degrees of longitude, or 43% of the circumference of the Earth. Mostly found in open grasslands or disturbed areas, including woodlands and disturbed forests from sea-level up to 1500m or more in elevation, it is variable in wing colour pattern on both upper and lower surfaces. The causes of this variability are uncertain, but temperature, photoperiod, rainfall, migration and perhaps underlying geographical differentiation may all play a role.”
The Clarence Valley Meadow Argus butterfly is represented by the image on lower right side taken on the Conservation Area for the cover illustration showing six Australian butterfly with various differences in colour pattern.

A small population of these fantastic little marsupials reside in the Dry schlerophyll forest ( Spotted Gum, Ironbarks and Bloodwood) on Sportsman Creek wildlife refuge. They are classified as Vulnerable and are patchily distributed from Cooktown to the Northern rivers area. They have largely vanished from inland areas. When alarmed they stamp their hindfeet on the ground and are known to use their tails to carry nesting materials. Image taken today in the Conservation Area of this secretive marsupial.

Olongburra Frogs are listed as Vulnerable and range from coastal areas near Fraser Island to Yuraygir National Park south-east of Grafton. Also called Wallum Sedge Frogs. Wallum is a banksia -dominated lowland heath ecosystem characterised by acidic waterbodies. An unexpected find at Sportsman Creek wildlife refuge. These frogs are usually found in rushes and sedges. “If you look at the colour in the groin or back of the thigh it is relatively easy as Litoria olongburensis has a bluish colour there while it is orange in both Litoria fallax and Litoria bicolour. The overhanging pointed snout in Litoria olongburensis is usually more pronounced – but then the broad white stripe down the side of the body is NOT a feature of Litoria fallax as this tends to end around the shoulder in that species.”

“The Garden Orb-weaver is one of the largest and most common spiders in eastern Australia. Adults spin web at dusk , feeding on a wide range of flying insects. The web is often eaten by the spider at dawn and a new web constructed the following night. Bites are rare, causing only local symptoms such as mild pain and swelling”. During the day they take shelter in bark and leaves.

According to Australian Museum Entomologist, Dr. Britton this species occurs as far south as central New South Wales and is also found in S.E. Asia, Indonesia and P.N.G. Adults are known to be fruit-piercing moths. Other species in S.E. Asia are known as “Vampire Moths” as some are known to feed on vertebrates and suck the blood of mammals.
