Ground beetle find

We found a really cool ground beetle in Hagley Park yesterday. None of these photos do it justice. It’s even cooler in real life.

We think the species is Megadromus antarcticus.

There is a guide to New Zealand ground beetles here. The Fauna of New Zealand Series No. 60 also covers this species.

NatureWatchNZ shows a fairly small number and area of observations of this particular species.

Origami

I have been making quite a bit of origami – more than a thousand creations. I have made 3 complex origami creations so far: a rabbit (Hsi-Min Tai), a fiery dragon (Kade Chan) and a beetle (Jo Nakashima).

If you want to try some origami for yourself, I highly recommend you start with easy models first!

Most stationary places will sell origami paper. You can also cut your own paper, though it is hard to get them square. We also make some of our own paper, including tissue foil.

The general rule of all origami is one square piece of paper, no cuts, no glue, no tape. All origami in this post follows that rule – except for the curlicues at the end which are made from long tapered strips.

I use tutorials on YouTube and some books. Here are a few of the results.

One of my favourite YouTube channels is by Tadashi Mori . I have also started on of my own, see here.

Several books I have found especially good are:

Curlicue: Kinetic origami

2-spotted lady beetles

Lady beetle larvae are very interesting.

After a few weeks of feeding on aphids, mealy bugs etc. they pupate.

After about a week they emerge as pale white or cream coloured lady beetles.

Over a period of a few hours they get their colour and their spots.

Here are some instructions, in case you would like to have a go at raising some yourself.
