Taslopa montana is a fairly ungainly looking leafhopper. Adults can either have wings, or not, so I'm not sure how to decide when a nymph has reached the adult form.. #Tasmania #Hemiptera #InverteFest
Side view of a thin and hunched leafhopper, about 6-7mm long. The rudimentary wings are beige but the rest is dark brown with pale hairs all over. The visible eye is very large and almost has a "brain fold" pattern of dark brown over green/cream. This was on the rim of a sample jar. Top view of the hunched leafhoppe. It's about 6-7mm long. The rudimentary wings are beige but the rest is blotchy dark brown with pale hairs all over. The eyes are very large and almost have a "brain fold" pattern of dark brown over green/cream.

A little more unusual for us is a freshwater fly larva (maggot). Found in a creek at Montrose #Tasmania. Hopefully someonewill recognise where it belongs in #Diptera #InverteFest
A macro of a full body view of a beige maggot. It is very small, slim lined with a slightly hardened head bearing orange jaws. The tail end is more interesting with 4 feathery prongs. You can see a few internal organs on the last half of the body. Detail of 3 of the four hairy prongs at the end of the body.

Another amazing Tasmanian fly, Deineches nudiventris. This is a hoverfly that seems to be a bit prone to getting trapped indoors in early March. It's about 2cm long. #Diptera #Tasmania
Face on view. The fly has large brown eyes but most of the rest is orange, including the legs. The mouthparts are a heavy triangle shape. Side on view of the fly. It has colourless wings, folded down the body, its back and legs are bright orange, apart from a patch of black on its back and large dark eyes. The legs are very bright orange. The main body has white hairs on the underside but the legs have orange hairs.

It's so exciting to add our own images of the endemic #Tasmanian leaf #beetle Ewanius nothofagi to our website. It's the only leaf beetle in Tasmania that feeds on Myrtle. Identification thanks to Martin Lagerway. Mount Field National Park, January.
Side view of a small honey brown coloured beetle on a reddish leaf blade. Top view of the honey-brown, oval beetle pointing down the image. The pronotum (thorax) is purely honey brown. The elytra (wing covers) have a base colour of honey brown but a three lines of black and two cream in the top half, two upside down Vs of balck in the middle, and a band of cream at the wing tip. It is on a browning leaf (I think it was Pandani).

A snipe #fly Atherimorpha sp. on the Lake Dobson Circuit in mid-January. #Tasmania
A side view of a small beige and black striped fly sitting on a deep green leaf. It has very pointed antennae and lots of hairs covering the body. The hairs come from very neat little puncture marks across the body. The eyes take up most of its head. Frankly, I think the neat little punctures are a highlight. There are more leaves in the background.

Beetles are strong fliers. Mites, however can only crawl. So that mites can travel further afield, they often hitchhike on beetles (phoresy). When the beetle lands somewhere favourable, the mites crawl off. These are sejine mites on a Ptinid beetle. January, Bruny Island #Tasmania
A brown, bullet shaped Ptinid beetle with one orange mite on its head and 4 on the one of the outer wings. The mites are very large for the size of the beetle, probably 1/8 the length. The beetle was attracted to light on a window at night, so the background is black from the flash photo.

The #lacewings are the sign of summer. This is not-your-usual green lacewing (Family Chrysopidae), it is one of the split-footed lacewings (Family Nymphidae). These catch me out every time! Osmylops sejunctus.
A green lacewing taking up the whole image. It was attracted to window light so the background is all black. The lacewing's body is mainly yellow and lime green. The wing nets are green and wing margins are black. The reflective eyes appear maroon. There are light black markings on the centre of the head and thorax.

Not so pretty is one of our #Tasmanian endemic scarab #beetles. Phyllochlaenia villosus
A beetle on a branch. The beetle is central to the photo and is facing right. the Head portions are black with golden hairs and the elytra (wing covers are a dark brown, fringed black and covered in lines of golden hairs. Tasmania does brown and hairy very well ;-)

We don't often add fresh images of Odonatans. Our lenses need to be too close to the insects, and the fast fliers don't tolerate us. This #damselfly was chilled in the early morning air and was happy to pose for a few different angles. A female Metallic Ringtail (Austrolestes cingulatus). #Tasmania
Side view of the front half of a metallic green damselfly. Between the segments there are orange lines. The eyes are brown. It is resting on a thistle, shown the right of the photo. Overhead (dorsal) view of the front half of a metallic green damselfly. Between the segments there are orange lines. The eyes are brown. It is resting on a thistle, shown the top of the photo.

Pison sp. These are not the most glamorous of #wasps but they work through crevices and holes and collect up live spiders to use as food for their own larvae. Fascinating lives and really important bio-control agents. Lucky people may find similar species building mud nests on brick walls.
A small black wasp foraging on a fallen, hole riddled gum tree trunk. This photo is selected to show some of their habitat. Detail of the small black wasp. Its antennae are attached low on the head. Its black eyes have notches on the inside, which helps to narrow down that this wasp belongs in Pison. The timber it is on is dry and rust coloured on the rotted inside, silver on the outside.

Gynoplistia cf. bella. A very pretty short-palped crane #fly. You can see this is a female as she has a long ovipositor to lay eggs. She also has quite subdued antennae when compared to a male which has longer "reindeer-like" flanges. You find these near damp places. This was at Penstock Lagoon.
A fly with long orange and black legs. The head and thorax are also black. In this photo you are looking just slightly on an angle to overhead. The wings are orange at the top, then barred black with 3 broad clear windows. it is on a leaf and its feet are just looped over the leaf margins. A fly with long orange and black legs, photo taken on the side. the head and thorax are mainly black. The thorax has some silvering at the sides. The antennae are quite feathery. The abdomen is long and mainly orange with a black join the the thorax and a couple of black segments close to the tip. There is an orange and black ovipositor.

How can anyone dislike a native wasp? This Ichneumon #wasp (Theronia steindachneri) parasitises other invertebrates - a natural biocontrol agent. Buckland, Tasmania.
Side view of a bright yellow glossy wasp with lots of caramel stripes down its segments. It is standing on a brown leaf. Face on view of the yellow wasp. Its a skinny native, not bulky like the European wasps. The large eyes are a caramel brown, and a largely bright yellow head. The long antennae are black and the forelegs are bright yellow.

These #Tipulidae craneflies must surely be some of the longest of our #Tasmanian endemic #fly species. The legs were way too long to fit into the frame.
A mating pair of orange/brown craneflies. The photo angle is lateral and the male is pointing up, the female pointing down, with only their genitals touching (I couldn't think of a better way to phrase this, sorry). The male has a more consistent orange/brown body very long antennae. The female is bulkier in general but with more black along her body. Both have very long legs that don't fit into the frame of the photo. A mating pair of orange/brown craneflies. The photo angle is from the top and the male is pointing to the left, the female pointing to the right, with only their genitals touching (I couldn't think of a better way to phrase this, sorry). The male has a more consistent orange/brown body very long antennae. The female is bulkier in general but with more black along her body. Both have very long legs that don't fit into the frame of the photo, and the long wings that are held perpendicular to the body is also cut off in the photo frame.

These Stomorhina sp. #flies are unusual finds in #Tasmania. The Tasmanian Bushland garden at Buckland had plenty just after Christmas. These are two different males. Females have their crazy eyes slightly wider apart. #Diptera
A side view of a fly, slightly smaller than your usual blowfly on a fluffy cottony flower bud. The eyes are large and striped purple and yellow-green. The thorax is fine rippled stripes of black and beige on the back, and the "tummy" is fluffy straw yellow. The thorax is black, orange and hairy. A almost undrside view of a different male fly. It's lightly smaller than your usual blowfly on a white flower. The eye is just in view and is large and striped purple and yellow-green. The mouthpart is really thick and long. The thorax is fine rippled stripes of black and beige on the back, and the "tummy" is fluffy straw yellow. The thorax is dotted black on orange and beige.

The Bright Copper is a bit too big for the lens, but worth noting here because we rarely photograph butterflies. The lenses we tend to use need to be very close to the subject and butterflies don't tolerate invasion of their personal space. They have to be unusually placid for us to have any luck!
A small butterfly with black and white striped antennae. The wings have broad brown borders and orange triangles inside. There is a coating of green tinged metallic scales across the thorax and upper wings. Buckland, Tasmania.

The honey brown beetle (Ecnolagria rufescens) is usually a fairly easy summer find around the state. It's also distributed from South Australia, right around the coast of the eastern states up to northern Queensland.
A coppery brown beetle with a fairly black head and legs. It was on small white florets with brown looking stamen.

How can an ugly beetle larvae make themselves look even more unpalatable? Gonipterus weevil larvae carry flamboyant flags of poo as an effective turnoff.
An early stage weevil larva. It looks like a bright yellow glob of something unpleasant. It has a slug like shape with no legs, and is covered by pinpoint black spots. The highlight is a knotted tangle of black "poo string" at the tail end. An older weevil larva that has the same shape as the earlier photo but is now a darker olive green. This poo sculpture is more spiral.

The very hungry stage of a leaf #beetle Paropsisterna cloelia. These larvae cluster together for safety initially but can also defend themselves by oozing hydrogen cyanide, benzaldehyde and glucose from lumpy terminal glands. The larvae on the outer position takes the defensive lead for the team.
One of the older larvae on a gum leaf. This has a caterpillar shape but the legs are tougher. It's largely yellow but has a black head, and last segments and a long black line running down most of the middle A group of 6 younger stage larvae that lack the black central stripe. The one on the far right has its back end up and defensive glands pushed out.
