one day old Dasypodia caterpillar

To my surprise the eggs from my previous post have already transformed into caterpillars, about 2mm long. They are supposed to eat acacia leaves, some species at least...So, I went to my garden and picked some leaves from in total 6 different species of acacias that I have in my garden. It seems to be a success, they do eat some of them at least, as evidenced by a little hole eaten in the leaf shown in the photo below (click on it to enlarge)...

one more view of Miss November...

The same moth as in the previous post but showing her frontal view.
And again her eggs (positioned in an array, sort of...) as photographed one day later; one can see that the colour is evolving from green towards brownish red. The eggs are not smooth but rather bumpy or perhaps even a bit "spiky"...? They remind me of seafood, for some reason...

candidate for Miss November, Bronze Beauty...

This moth is quite large, with two large blue spots and a pattern of several (three) prominent parallel zigzag lines. I spotted her in our semi enclosed car port last evening, she was sitting still on the brick wall there. I took her inside the house for one evening/overnight and she laid some eggs, as seen on the photo (click to enlarge). The eggs are greenish and are roundish/ flat (cylindrical). Her scientific name is Dasypodia, common name is "Southern old lady" moth or simply "brown house moth", what a boring name (but at the same time quite a descriptive name...) The caterpillars feed on several (at least) acacia species. Will observe the eggs, and she can go outside, perhaps she will produce even more eggs...

The case of Private Pancake = caterpillar feeding on grass...

Recently I have been showing translucent green caterpillars feeding on eucalyptus leaves; but I have also spotted a different green larva feeding simply on grass leaves. I have observed that not only it feeds on grass but it also hides in the blades of grass, by which I mean it rolls itself into a single blade of grass (rolled lengthwise around his body). One can see some white silk thread that he used as a "glue" for rolling/wrapping the blade of grass around his body (click on photo to see details). I decided to call him Private Pancake because he reminds me of soldiers dressed in green uniforms (the grass) and a simple elongated shape of the rolled pancake...
How about edible uniforms for soldiers, inspired by this guy?...

Houdini 2

As I have explained before, Houdini has disappeared, maybe he is underground, who knows?
So, today I have started afresh with "Houdini 2". Will observe him much more closely this time and will report!

translucent caterpillar feeding on eucalyptus

Here it is, one of my latest caterpillars; I have no idea what will grow out of it...
It is feeding on eucalyptus leaves. Looks a bit translucent...
I have called it Haudini, because he disappeared recently, like that famous circus magician, not sure whether he went underground or what...

classic Australian icon

(No, not Don Bradman...)
Yes, I am talking about our iconic Bogong moth. They migrate south in spring to survive hot Australian summer in the crevices and caves of high mountains. I have seen several of them recently in Canberra, in my garden, on sidewalks, under my main entrance door, etc. They are looking for dark and cool crevices to help them preserve their moisture. I did not dare to try to eat one (they are edible), partially for fear of arsenic content, it was reported in the past that for some unknown reason some of them at least contain poison, and partially because I have no confidence in my insect cooking skills. Apparently the way to cook them is first chill them in the freezer (that should kill them with minimal or no pain; insects are cold blooded of course) and then use just flame of one match to cook one moth. Dewing and de-leg and "enjoy", hi, hi... Fat content nearly 40%...
There was a cafe in Manuka serving fritatas made out of Bogong moths (and other interesting bushtacker items). It existed a few years ago, this year I wanted to go and try their Bogong moths but could not find that cafe in the Yellow Pages anymore, looks like the menu was too exotic, not enough customers perhaps, what a pity...

new kids on the block

About one week ago I had a visitor, so called Magpie moth (Nyctemera) , it is called "magpie" because of black and white wings, here is her photo showing the characteristic top view. This type of moths are also called "tiger moths" because their abdomen often has black and yellow stripes; they mimic stripy wasps trying to scare (and warn) whoever would be tempted to eat them. Picture showing the strips on abdomen is the second one below.

The moth was a female and has left a few eggs on the twig it was sitting on, each egg smaller than 1mm.... 
And today several hairy caterpillars all emerged from the eggs. They are now about 2 mm long and very hairy. They feed on Senecio. (Photo of the caterpillar below was taken against the backdrop of a blue plastic box.)
The bristles are long. (In general one should avoid contact with hairy caterpillars as some species can cause severe itching, even can sting and/or cause blindness. Maybe this particular species is not dangerous, but you never know for sure...)  
Interesting thing about tiger moths is that they can produce sounds (but in frequency range beyond human hearing abilities). Perhaps such sounds serve to confuse bats or discourage bats from eating tiger moths as they are not tasty anyway.

Second seductress

In my very first post on this blog I have shown so called Pink Bellied Moth (Oenochroma vinaria). It is fairly common in native gardens as the caterpillars feed on hakeas, grevilleas and other Proteaceas. Last winter I have found in total 4 pupae on the edges of the concrete path in my front garden, under the loose leaves. Here is how they looked like (one pupa shell is empty, after the moth has emerged and the other shell still full):
Yesterday last of the moths from the found pupae has emerged. They always emerge at night or early morning perhaps, I have never witness the process. What has emerged was a female moth again, I think. 
Below are her photos taken yesterday, the blue flower in the background is an iris. And why do I think it is a female again and why do I call her "Second Seductress"? Well, because of her behavior, she is "calling" male moths by extending out her pheromone gland at the end of abdomen (click on the last photo to see it better). Chemical seduction. I let her escape last evening into the darkness of my garden, I hope it is not too cold at night, and I do hope she will find a mate and will produce eggs for next generations of pink bellied moths to come...

His Greenness lost his greenness...

Photo from today; I used to call him "his Greenness" when he was still a green caterpillar (one week ago or so), but now it does not seem an appropriate name anymore...
He is not moving anymore, stopped eating parsley, lost his green color completely; his look now reminds me of a lump of candle wax; the texture  looks a bit grainy (click on the photo to enlarge)...I am not sure whether it is completely "normal", perhaps there are parasites inside?...Brr...Or am I worrying without any need?
Time will tell...
Yes, now I know, that grainy structures are actually cocoons of wasp parasites! The green caterpillar is no more!
