We have some beautiful beetles here, and some that annoy me by eating trees that I would like to have survive, but I’d never paid much attention to the little black beetles that crawl around on the ground.
Then in March we had a visit from Kip Will from UC Berkeley who was interested in carabid ground beetles. (Not rabid, as I thought when he first said it.) To check out what we have, we set up pit traps (plastic beer cups buried in the dirt) at various locations in the Box Gum woodland, helped by Fabian and Martta.
In the evening we also set up Kip’s bright light on a sheet to attract flying beetles and other insects, but few were about because of the rain. 
It’s extraordinary what variation you find among things that at first glance look to be all of them black and tiny.
The black and yellow one was a bombardier beetle (pherosophus), which can eject a spray of explosive chemicals at its enemies or prey. Charles Darwin had a bad experience with an English bombardier:
I must tell you what happened to me on the banks of the Cam in my early entomological days; under a piece of bark I found two carabi (I forget which) & caught one in each hand, when lo & behold I saw a sacred Panagæus crux major; I could not bear to give up either of my Carabi, & to lose Panagæus was out of the question, so that in despair I gently seized one of the carabi between my teeth, when to my unspeakable disgust & pain the little inconsiderate beast squirted his acid down my throat & I lost both Carabi & Panagæus![7]
We didn’t try to bite any of the beetles.
From the beer cups and bed sheet traps, Kip identified:
- Clivinini – 3 spp (narrow body, some pale) sandy soil, riparian, predatory
- Sarticus (1 large species) eat grass or seeds (an old Gondwanan species)
- Prosopgmus sp (grass habitat, maybe seed eating?)
- Harpalini (larger, pale legs) Grass seed eaters
- Loxandrus ?gagatinus riparian, muck lovers
- Harpalini (very large, black legs) grass-seed
- Pherosophus sp – predator (larval on water beetles) “bombardier”
- Harpalini (small, pale legs) eats seeds and grass
- Chlaenius – predator, scavenger
- Pseudoceneus sp – maybe predator
- Mecylothorax punctipennis ?
Most of these were grassland specialists. In the future we’ll be able to see if there have been any increases in the numbers of woodland or forest beetles, as the canopy of the trees we’ve planted in the Box Gum area grows. Kip also suggested that some research on what prompts the transitions to different instars (these beetles can go through 3-7 different phases) could be a good idea.
What an amazing world has been there under the grass and twigs all this time.
Of course, that’s not all that easy to do. 
Out on the hills, “what comes” is pretty good right now. 
ess, various sprays etc). In the last two years we have planted 30 to 50 of these which despite some setbacks in the way of frost, not to mention last autumn’s endless dryness, have been doing well. The main challenge is transporting the big pots (this year big sections of pipe) up to where they’ll be planted. The rest of our plants come from Murrumbateman Landcare, Greening Australia or Damian DiMarco’s nursery on Wallaroo Road, making as wide and balanced a range of species as we can manage. 
All those months waiting for rain in the autumn, and now we have too much. 
The Great Aerial Ocean above our heads, for me, is a reminder that we all live on the one planet. Only a thin band of atmosphere comes between us and the inhospitable vastness of space. 
Our lovely neighbour Cathy Campbell has a new project. It’s called “Managing Mange in the Mullion” (that’s the title of the Facebook group also) and involves counting wombats, working out how many of them are affected by
