Two Interesting Inverts in Two Minutes



Yesterday I was early to a rendezvous and killed a few minutes in a piece of nearby bush – some people are easily entertained!

Yellow Crane Fly
After ticking one of these in the Bunyip State Park some weeks back, I didn’t really expect to see another quite so quickly. Obviously in this area of West Gippsland, this species is a little more prevalent than I expected.


It’s important to note that the Crane Fly is not responsible for the chewed euc leaf next to it. Crane Flies do not feed at all apparently during their adult phase.

Red and Black Spider
I found this little arachnid under some bark on a tree trunk. The Museum Victoria spider page tells me it is a common species that because of its colour is sometimes confused with the much more fearsome Redback.


Seemingly, Red and Black Spiders do not have a particularly harmful bite. The enlarged pedipalps on this individual probably indicate that it is a male. The pedipalps are used more like arms or antennae to detect and capture prey and in males they are also used to transfer sperm to the female. Pedipalps are not jaws and do not inject venom.

  1. I've never seen or heard of the Red and Black Spider - maybe it's not one we get in SE QLD. It's beautiful though!

    Craneflies are a dime-a-dozen up here however, except our common species has a different pattern on the thorax.

    Lovely photos!

  2. A couple of nice finds.

    Nicely marked Cane fly!

    Scary looking (though beautiful) spider :-)

  3. The world of invertebrates is just so diverse and fascinating - so much to see and learn. Thanks for looking in.
