Dogs sniff out endangered insects

Three dogs have been trained to find endangered insects, and they could revolutionise conservation practices.

The successful dog detection trial saw every dog find the endangered insect.

Three specially-trained dogs have located the endangered Alpine Stonefly, also known as Thaumatoperla alpina, at Falls Creek in Victoria.

That makes the three dogs, named Bayar, Judd and Sasha, scientifically-proven good dogs.

While the Alpine Stonefly is the largest stonefly in Australia, it’s one of the smallest animals a dog has been trained to successfully detect in its natural habitat.

Lead researcher Julia Mynott, from La Trobe University’s Centre for Freshwater Ecosystems in Albury-Wodonga, said detection dogs are usually trained to sniff out animal nests or faeces, not the animal itself.

“This is an exciting and innovative way to revolutionise how we gather data on our endangered species, no matter how big or small,” says Mynott.

Dogs find the elusive critters

“In the past, we’ve been restricted to traditional methods of detection when looking for stoneflies, which include visual surveys and aquatic sampling.”

Despite their bright orange and green colouring, Alpine Stoneflies are difficult to find, especially when they’re in water.

“The Alpine Stonefly is an aquatic insect that hatches in the streams of the Bogong High Plains, where it lives for up to two years. The larvae often burrow underneath cobbles; debris; or boulders, while the adults only emerge between January and April to reproduce.

“With all these factors in mind, it’s easy to understand why the traditional detection methods can be time consuming, and for the larvae, fairly ineffective.

“Right now, we have no idea of the population size of the species.”

Good dogs could track other endangered insects

Building on the success of the first trial, Mynott hopes to transfer the technique to a similar species – the Stirling Stonefly or Thaumatoperla flaveola, that is found at Mount Buller and Mount Stirling.

Preliminary trials on the Stirling Stonefly suggest detection dogs can transfer their conservation training from one species to another.

“Insects might not be that appealing to everyone, but they are important for ecosystem functioning, particularly in alpine areas that are environmentally important and under threat from climate change.”

“We chose stoneflies as a starting point because they’re such an interesting animal. They have wings but are flightless. They’re sensitive to changes in water quality and, despite their role as one of the top predators in the alpine region, their inability to fly makes them vulnerable to other predators in this environment,” says Mynott.

“Now that we’ve successfully trained three dogs, we’re hoping to secure funding that will enable us to conduct future surveys on the Alpine and Stirling Stonefly, and on a third species of stonefly that can be found at Mount Baw Baw and the Yarra Ranges.”

In addition to the detection dogs, the research team hopes to expand their current environmental DNA (eDNA) work on threatened stonefly species, which is a detection method the researchers are using in conjunction with the dog trials.

How to teach a dog to find insects

Owned by local community volunteers, the dogs were trained at La Trobe’s Anthrozoology Research Group Dog Lab in Bendigo, where they spent seven weeks memorising the odour of the Alpine Stonefly in a specialised training program.

The dogs were introduced to the unique insect odour in controlled settings where researchers could determine whether the dogs could reliably detect their scent.

Once this was established, the dogs learnt to search small areas of bushland for the insect. Once they found their tiny target, they were rewarded with food and ball games.

Researchers ensured that the dogs did not directly interact with the insect. Instead, once located, the dogs were trained to ‘point’ to the endangered insect with their nose, from a short distance away.

The Falls Creek trial was highly successful, with all three dogs and their volunteer handlers finding wild Alpine Stoneflies in their natural habitat.
