Ken is our Senior Curator of Entomology.

On Monday last week, live images of an attractive Australian lady beetle popped up on the BowerBird citizen science website photographed west of Portland, Victoria. The photographer recorded seeing more than 50 beetle specimens in a small swampy area.

There is a wonderful CSIRO lady beetle website with a gallery of images for all known extant Australian species, however we were unable to match the photo to any in this gallery. So we sent the BowerBird images to the Canberra scientist who created the website. His initial reaction was to doubt the veracity of the locality data as he claimed this was not an Australian species. I reconfirmed the Australian locality with the photographer so we began to wonder if this was an invasive species.

The images were then forwarded to the world lady beetle expert at the Natural History Museum (NHM) in London. We received news on Friday night from Roger at the NHM that this is a species "back from the dead". A species not seen or recorded for more than a 50 year period is considered to be extinct. There are only 4 known specimens of this species in collections (2 at the NHM and 2 at Museum Victoria) - the last specimen was collected in 1940!

This is indeed an Australian species, Micraspis flavovittata (Crotch, 1874). I remember we once had an exhibition at the museum called Extinction is forever…. and so it is, until someone finds it again! The only known localities of this species were Narbethong and Kallista so the Portland location is well west of these previous records.

Many people contend that the best citizen science projects are those in collaboration with professional scientists. Personally, I love the serendipity of citizen science discovery alone.

Redmap Australia launched

Di is Senior Collections Manager in our Sciences Department and is absolutely passionate about the amazing and unique fishes found in our waters.

Museum Victoria staff are involved in a fantastic citizen science project that's taking a giant nationwide leap from its starting point in Tasmania. With today's launch of the Redmap Australia website, the community is being asked to look out for unusual occurrences of species in the seas around Australia. These community sightings will help reveal if fishes and other marine species are shifting their ranges with the changing climate.

The website, also known as the Range Extension Database and Mapping Project, began in Tasmania in 2009. Already Tasmanian fishers and divers have logged hundreds of unusual sightings including Eastern Rock Lobster, Southern Maori Wrasse and King George Whiting, all spotted further south than usual.

  Southern Maori Wrasse Southern Maori Wrasse (Ophthalmolepis lineolatus) are uncommon in Tasmanian waters but more and more are being reported to Redmap along the north and north-east coasts of Tasmania. This one was snapped by diver Emma Flukes off the coast of St Helens.

Redmap founder, Dr Gretta Pecl, is a senior marine scientist at the Institute for Marine and Antarctic Studies (IMAS) at the University of Tasmania. She says Redmap "taps into the knowledge - and eyes - of thousands of fishers, divers and swimmers to track changes in fish distributions in Australia's vast coastal waters." Some three or four million Australians go fishing or diving at least once a year.

The Redmap website encourages members to share photos and anecdotes about turtles, octopus, lobsters, corals, seaweeds, urchins, prawns and marine mammals. A network of marine scientists around the country will review each photo to verify the species' identity and ensure high-quality data. Redmap aims to become not only a continental-scale range-shift monitoring program along Australia's vast coastline, but also engages Australians with marine issues using their own data.

Some seas along the Australian coast are warming at three to four times the global average. We're not sure how species will react to warmer waters - some may adapt, others may search for new habitats, while others may disappear. New arrivals of some species, especially recreational fishes, may actually benefit some communities. Understanding the movement of other species of marine pests may help minimise the risks to ecosystems or fisheries. In Victoria, fishers and divers have already been telling us about rare or uncommon fishes they've seen - including Blue Groper, Cobia, Rock Blackfish and Spotted Grubfish. Gathering sightings over time will show if these species are simply seasonal migrants, one-off visitors, or are here to stay.

I'm the coordinator of Redmap VIC and the MV team includes Martin Gomon, Julian Finn, Erich Fitzgerald and Kate Charlton-Robb. Although we'll officially be tracking some 35 species in Victoria through the Redmap project - such as octopus, Greynurse Sharks, Harlequin Fish, Striped Marlin, whales and dolphins - we're very keen to hear of sightings of other rare or uncommon species seen along our coast. You can get involved by becoming a Redmap member, signing up for the quarterly newsletter, liking Redmap on Facebook, and logging unusual marine life at www.redmap.org.au.
