I collected this specimen off our lemon tree. I’m not entirely sure how it died, but it’s possible disease got the better of it.

This species is often called the Orchard Swallowtail, as they feed on trees in the Citrus genus (lemons, oranges, tangerines, etc.). There’s a few swallowtail butterfly caterpillars that feed on Citrus, but this species is the most common sight for me.

Now, I know what you’re thinking… “Hey! Why are you showing us pictures of bird poop?” At the very least, it’ll be a fleeting thought to start with and I’d know because that is exactly what went through my mind when my husband excitedly raced into the house and told me to grab my camera. He lead me to the plum tree and pointed at the leaves. “Tiniest bird poo I ever did see…” I thought to myself. “I think they’re a caterpillar!” Said my husband excitedly as he knew he had found something for my blog. He was right. This was no bird poo. It was just trying to LOOK like bird poo. ***CORRECTION*** I originally thought it was a really small instar of the Orchard Swallowtail but someone has brought to my attention that they’re sawfly larvae!! Just more things that want to look like poo! Thank you for the correction, darkinternalthoughts! Found in Monash, ACT, Australia.
Yesterday I was startled to find this enormous fellow happily gobbling entire branches bare on my finger lime tree. Fortunately I'm a lazy-ass gardener who'd let the root stock set loose a wild branch and done nothing about it. Last time I checked it was bigger than the poor little finger lime. NOT ANYMORE. CATERPILLAR TO THE RESCUE!
Every branch he's been on is bare. Take that, unruly rootstock!
I decided to look up what he'll become and it's glorious. The photo below is not mine, it's from Wikipedia.
That's the female. They're called Papilio Aegeus. Nice to have helped out an Aussie native. I'll update if he survives to pupate. Fingers crossed!
@rayify submitted: hello, no need for ID (think it's papilio aegeus)! it was nice to see this on a sunny day after a lot of miserable weather so i wanted to share
Yes, an orchard swallowtail. Specifically a female! I love her :)

usually more patience required than I have, but he was very good for a short while. will check but maybe: Orchard Swallowtail Butterfly Papilio aegeus
Not the most pleasant post, but I was curious to see what would become of the body.

The caterpillar suffered all the symptoms of disease that I am aware of. Sudden diarrhea, weakness, eventually leading to dropping dead completely. Caterpillars are highly susceptible to disease, so washing your hands thoroughly is important.
The corpse turned completely black, and developed a hole near the rear of the caterpillar. I’m not sure why this hole appeared.
An orchid swallowtail butterfly (Papilio Aegeus) at the Melbourne zoo butterfly house. This was in a very room but it was fun to watch the swarms of butterflies landing on everyone there.

This butterfly was huge! A really beautiful thing to see.
Papilio aegeus, the Orchard or Large Citrus Swallowtail. The largest butterfly you get around Sydney, and a minor pest of citrus. Personally, I'll happily have a few caterpillars around the place in return for more butterflies like this. Pretty much restricted to the east coast.
While their ARE native citrus in Australia - the Finger Lime and Desert Lime, for example - the larvae also feed on other plants, including Boronia, and Prickly-Ash.
