Red Triangle Slugs in Angophora

Red triangle slugsRed Triangle Slugs found by Jen and the team as they removed Strelitzia’s (Strelitzia nicolia) – a garden plant that takes over areas of bushland and continues spreading taking over native shrub and ground plants – if not removed.

This photo is from Angophora Reserve Avalon where Dragonfly Environmental are ‘ Bringing Back the Bush’ – well getting out the grass and ground weeds spread from gardens and keeping the fuel load low along the interface between houses.

Identification
The Red Triangle Slug is Australia’s largest native land slug. The distinctive red triangle on its back contains the breathing pore.

Size range: 14 cm

Distribution
East coast of Australia: Queensland, New South Wales.

Habitat
Red Triangle Slugs are found in urban areas, forests and woodlands and heath.

Feeding and Diet
The Red Triangle Slug is usually found grazing on microscopic algae growing on the surface of smooth-barked eucalypt trees, leaving behind scalloped tracks as it goes. If given the chance, it will also remove bathroom mould.

Other behaviours and adaptations
Native slugs can be differentiated from introduced slugs because they have only one pair of tentacles, while introduced snails and slugs have two pairs. Also, the saddle-shaped mantle seen in introduced snails is reduced or absent in native snails and slugs.

Classification
Species: Graeffei
Genus: Triboniophorus

Seasons & Cycles

Nature-Based Walk & Talks – Aboriginal Guides – Free Activity

This Sunday 25 August, the final ‘Seasons & Cycles’ nature-based walk & talks for 2013 will take place at Gibberagong, Bobbin Head in Ku-ring-gai Chase National Park from 10am – 12:30pm. This popular activity provides people with the opportunity to enjoy and connect with our local natural places and the cultural heritage within these areas.

Come and join the ever-flamboyant Les McLeod, Aboriginal Discovery Ranger and the fascinating Fran Bodkin, D’harawal knowledge-holder and author. Hear stories and knowledge of our natural environment, while you are guided on a walk in this beautiful area, which is rich in culture, history, native food and medicinal plants.

Event organisers Tina Demetriou Director of ‘The Event Consultant’ and Mia Dalby-Ball Director of ‘Dragonfly Environmental’ provide a unique combination of sustainable event management, environmental science and education.

Together they have created popular events that bring together the understanding of nature and biology with fun, creative and engaging outdoor activities that have now been enjoyed by nearly 1000 participants in the last few years.

Tina Demetriou said “Aunty Francis is well known for captivating audiences for hours with her passionate delivery of fascinating facts about the natural world”, said Demetriou. “Additionally, Les McLeod is one of the most intriguing & charismatic presenters and will always fascinate and entertain”.

Often Sydney-siders have associated Aboriginal cultural experiences with more remote areas of Australia, yet these activities allow locals to connect with the cultural heritage right here in our own backyard.

This free event is presented by the Hawkesbury Nepean Catchment Management Authority and supported by Hornsby Shire Council.
