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.

Steaming through Williamstown

Matilda swapped a life working as an engineer for a life curating the museum’s historical Engineering collection. She’s very curious about how stuff works, how it’s made and why. If a machine’s got a switch, she’ll definitely flick it.

A very satisfying part of my job is participating in the Scienceworks Working Machines program. How else would I find myself steaming down the main street of Williamstown in a historic steam truck a couple of Sunday mornings ago?

A small and dedicated team of staff and volunteers help demonstrate some of our heritage vehicles to the public on four selected Sundays a year – Machines in Action Days. On four other Sundays we are busy learning and practising the skills needed to safely operate such historic machinery. I spent the first couple of hours in the morning bringing our Cowley Traction Engine up to steam ready for the team, and then it was time for some training by Richard on the Super Sentinel Steam Waggon (circa 1924).

Our heritage vehicles have special permits so they can travel on public roads. So on some days, instead of practising around our arena, we get to survey the streets of Spotswood and Williamstown from behind the wheel of one of our steam-driven engines.

So what skill did I practise during that trip? Well, it was basically shovelling the coal into the firebox of the boiler to maintain the correct pressure to suit Richard’s travel speed and load. And make sure the water to the boiler was kept topped up. Sometimes I had time to wave to people in the streets, those enjoying their breakfasts, and even snap a few pictures. But not many – I had too much coal to shovel.

We got as far as the historic Williamstown Timeball Tower before it was thought best to head back to Scienceworks, before we ran out of coal. No handy coal depots nearby any more.

Finding the Orchard Pacemaker

A recent Discovery Centre enquirer asked whether there were any images of a Sunshine Massey Harris tractor in a particular trade literature document in our collection. Unfortunately that document did not have the picture she was hoping for. But, as we have such an extensive holding of Sunshine Massey Harris material, I was convinced that there must be a picture of this tractor somewhere amongst it all. So armed with her photo of the tractor’s radiator only, the hunt was on.

I started with the Price Books. They are not just lists of numbers and descriptions; they often have small illustrations or photos of the product. From these I was able to see, based on the shape and features of the radiator, that the particular tractor was the Orchard Pacemaker model. But the images were too small to make out the feature she was most interested in – the 'SUNSHINE MASSEY HARRIS' impression on the radiator. The Price Books did however reveal that these tractors seemed to have only been available between 1940 and 1942.

After more searching, I finally found a photograph in a general publicity brochure for tractors (dated 1941) of the Orchard Pacemaker, clearly showing the radiator.

It was not an easy search and most times these types of searches turn up nothing. So it makes these little finds all the more special and it’s immensely satisfying to be able to provide more information to the public.

Paul edited the MV Members' magazine Six Months over the past year.

Work starts today on a green upgrade of the Melbourne Museum plaza. The raised seating areas at both the Nicholson Street and Rathdowne Street ends of the plaza between the museum and the Royal Exhibition Building are being remodelled into two large planter boxes, each planted with 16 Tristaniopsis laurina 'Luscious’ trees.

These Australian natives, also known as Kanookas or Water Gums, are a common sight in city landscaping. They have bright yellow flowers and quick-growing shady canopies. The trees will grow between 4.6 metres and 9.1 metres tall.

Under the Plaza Planters Project, which has now won agreement from both the Melbourne City Council and the Museum Victoria board, the two 864-square metre boxes will also be grassed over with lawn (as well as mulch at the base of each tree). The three long seats currently in each space will remain, creating a more comfortable area to take in Melbourne’s unique Museum precinct.

The revitalised plaza will help to visually connect both buildings with the established gardens on either side. As well as adding some extra greening to the central corridor through the Carlton Gardens, the trees will create an intriguing contrast of natural beauty alongside the architectural splendour of both Melbourne Museum and the Royal Exhibition Building.

Works are due to be completed by mid-October. The new seating areas will be ready and accessible well before the start of summer—which is just the right time to see the trees in full bloom.

Biodiversity Month

Rosemary is a Senior Collection Manager. She was Senior Curator of the Many Nations section of First Peoples.

Australian endangered species registers make sobering reading. They list animals and plants that are vulnerable, threatened, endangered and extinct. Each listing includes detailed information such as scientific and common names, habitats, particular threats, estimated numbers and management plans.

Absent from these lists are the Aboriginal language names, cultural knowledge and connections that for thousands of years have been celebrated through song, ceremony, stories and art. All of these animals were named and included in Aboriginal culture prior to being ‘discovered'—and endangered—post-contact.

The Many Nations section of First Peoples provides a unique opportunity to mark this National Biodiversity Month by learning from Aboriginal artists and material culture about their deep connections with over 150 of these animals and birds, including around 20 that appear on the Threatened Species list.

The Animal Creations case contains many endangered animals: Nganamara, Dilmirrur, Kuniya, Ulhelke, Mala, Mewurk or Goodoo, Itjaritjari, Purinina, Garun, and Pokka. There are also several introduced species: the Ngaya, Rapita or Pinytjatanpa, and Camel, whose stories connect to the demise of the Mitika, Wintaru and Mala. Other cases also contain beautiful pieces connected to listed animals and birds including the Gunduy, Gudurrku, Puntukan, Bilby, Rufus Bettong, Black-billed Stork, Stone Curlew and Kakalhalha.

The latter is a beautiful pink bird that has been given several names since it was ‘discovered’ – firstly Major Mitchell's Cockatoo in honour of explorer Major Sir Thomas Mitchell. It was also named Lophochroa leadbeateri to commemorate the British naturalist Benjamin Leadbeater. To the Arrernte people, this important bird remains known just as it always has been: the Kakalhalha, for the sound it makes. It likes to eat some of the same bush seeds as the Western Arrernte, making it a good indicator of the harvest season, telling the community when it is time to collect the seeds for damper.

Some of the animals on the Threatened Species list include these from the lands of the Pitjantjatjara in Central Australia, the Yorta Yorta in Victoria and the Trawulwuy in Tasmania. Yorta Yorta artist Treahnna Hamm's Mewurk or Goodoo (Murray Cod) artwork highlights the declining health of this magnificent fish and its river habitat.

Most commonly known as the Tasmanian Devil, the Purinina made by Trawulwuy artist Vicki West is made from kelp, another species in decline. Said Vicki in 2012: ‘I like using kelp, a plant fibre from the ocean, the old people used it to create the water carriers; I use it as the metaphor of survival… The Devil plays an essential role in the cleaning of and caring for our country through scavenging. I find it ironic that the medium I chose to represent survival has been used to create an animal under threat, itself endangered.’

Itjaritjari (marsupial moles) live in the sandy river flats and sand dunes in the desert of inland Australia. They are rarely seen and spend most of their time underground. Aboriginal traditional ecological knowledge is crucial to piranpa (western) science's understanding of this reclusive animal. Virtually all Itjaritjari specimens have been captured by the Traditional Owners of the desert, who play an integral role in Itjaritjari research. The Itjaritjari has great cultural significance also: during the formation of the western face of Uluru, a number of caves and potholes were created by a Totemic Being called Minyma Itjaritjari.

Increasingly, joint management and conservation projects rely on the cultural knowledge and expertise of Aboriginal communities to protect animals at risk.

Simon is a presenter with MV’s Outreach Program. He travels all over metropolitan Melbourne and regional Victoria in one of our two Outreach vans with a dinosaur sticker on the side. You should give the vans a toot if you see them.

Quick! Look at this fossilised fern!

You are one of the first people to see it!

We at MV’s Outreach Program travel all over Victoria, bringing the MV’s collections to those who may not be able to get to one of our museums. During our presentations we encourage those we meet to explore and interact with the interesting things we have brought on the road that day.

This is one of the fossils we use in the Outreach Program’s Dinosaurs and Fossils presentation to communicate the idea of plants being an important part of the fossil record; it’s not all T. rex claws and Stegosaurus tail spikes. (Although, we do have a T. rex claw and a Stegosaurus spike, and they are pretty awesome.) We have fossils with leaves, seashells, bones and teeth for our audiences to handle and investigate.

During a kinder visit yesterday, one of our keen, young palaeontologists was testing his revolutionary new ‘drop’ technique and managed to unearth a new fossil running across and through one of the specimens.

As we gazed upon the freshly split rock back in the office, it occurred to us that only a handful of people – the probably-panicked kinder rock-dropper, our Outreach presenter, and a few of our team – have ever seen this fossil. So we thought it would be only right to bring you into the fold and invite you to be among the first humans to ever set eyes on it. The count currently stands at approximately six people, or seven if you include Kate who proofs the blog posts before they go out. I'm 004, but she’s lucky to get 007.

So get your peepers around these pictures and join our very exclusive club. We’re going to get jackets made!
