Brisbane Storm 20/05/2009

Brisbane had its heaviest rain in 24 hours for decades on Tuesday night and Wednesday morning. Having spent several years in Darwin I love heavy rain and generally regard the 'severe' weather in Brisbane as pretty mediocre. I'm sure people who have had their houses damaged wouldn't agree. Anyway, the creeks were close to bursting their banks in several parts of Brisbane and actually did so in the suburb of Windsor. In our neck of the woods (a tributary of Bulimba Creek called Phillips Creek) I was kicking myself for not having my camera on me during the storm when we were out driving. The water was boiling under the bridge just upstream from us and actually over the bridge downstream from us.

The bike-path bridge a short distance downstream from us a few hours after its peak. It crosses a storm water channel leading to Phillips Creek about 10m away.

Tracking growth

I thought it would be a good idea to track the growth of several plants around the garden. Generally it is very difficult to tell what a plant is until it has grown past its initial leaves so I'm starting early. There are also a couple of Hibiscus shots related to the previous Hibiscus inhabitants entries.

Gooseberry seedlings

Silverbeet seedling

Brussel sprout seedling

Hibiscus stem closeup. It's a spikey one!

I planted it a bit too close to the neighbours fence but after recent persistent rain (over a few weeks) it started leaning out from the fence. It is growing in clay soil. However the top is now pointing skywards again and it seems none the worse for it.

Hibiscus inhabitants 2

I'm interested to see what comes out of this egg case?

Transient wasp. Possibly a Hatchet wasp? Hatchet wasps attack lawn grubs.

Shy spider. It is probably a Green Jumping Spider, Mopsus mormon (ID source - Brisbane Insects and Spiders)

Transient sap sucking bug

This little spider appears to be camouflaging itself with nearby caterpillar frass... or perhaps the frass just landed there.

Hibiscus inhabitants

I thought I'd focus on beasties that inhabit particular plants from now on (not too rigidly of course). These ones inhabit or visit Hibiscus splendens (need to double check the ID and get a photo as well).

I believe this is a Katydid rather than a Grasshopper due to the very long antennae.


I haven't confidently IDed this caterpillar yet but think it might be in the genus Amonis, which is a moth.

I'm assuming this is a later instar (molt). There were about 6 caterpillars when I looked a few days ago but there appear to be only 2 left.

Environmental Science

I'm seriously considering moving away from computing as my main job focus and instead using my IT skills to complement working in environmental science. Right now I'm going through job sites, university sites and government web sites identifying the kinds of work available. The area is as rife with acronyms as IT. Here are just a few.

EMP - Environmental Management Plan
EIA - Environmental Impact Assessment
EIS - Environmental Impact Statement
EA- Environmental Assessment
GIS - Geographic Information System (essential)
ABRS - Australian Biological Resources Study
TCM - Total Catchment Management
CWMPs - Catchment Water Management Plans
ESD - Ecologically Sustainable Development
SoE - State of the Environment (the IT acronym means 'standard operating environment')
NPI - National Pollutant Inventory

I've a lot to learn not only about government departments managing the environment but also about private firms carrying out assessments, surveying and doing site rehabilitation. At the federal level there is the Department of the Environment, Water, Heritage and the Arts. The QLD government has the Department of Environment & Resource Management (comprised of the former Department of Natural Resources and Water, and the Environmental Protection Agency). How they can separate that from Infrastructure and Planning I don't know but hopefully they work closely together. You would think Primary Industry and Fisheries would belong under natural resources as well. The logic behind it is probably interesting.

Slimey and spikey

I have no idea what this nymph develops in to, perhaps a ladybug?


What is this? It looks like a cross between a slug and a beetle...
This furry spider likes to hide during the day and spin its web at night. Probably a Garden Orb-Weaver (Eriophora transmarina - ID source - Wildlife of Greater Brisbane).

Moths

It's been a while since my last post. My daughter is now 3 1/2 months old. Enough said :-)

This little beastie was sitting on a cupboard handle in the kitchen. Its markings almost look like acrylic paint. It is a Green Blotched Moth (Cosmodes elegans - ID - Ozanimals.com). We don't have any Lobelia or Verbena mentioned on the Ozanimals site so it must have come from a neighbouring yard.

This very large moth (probably a Hawk Moth) had the misfortune to be discovered by our cats and is thus looking rather battered. I kindly relieved its suffering by feeding it to our chooks. At least they don't play with their food!

I know it's not really an expression but the moth does look pissed off.

Another small moth attracted to the light in the bathroom. Its colouring is of course brighter but I haven't learnt how to adjust for the necessary flash.

One more moth shot. There were of course many more visitors but I didn't always have a camera nearby and charged. There was a magnificient praying mantis on the front door frame last night but the camera battery was flat!

Flies and flighty

Skinks are a bit flighty so this one must have been a bit cold. I'm sure the residual heat from the morning sun on the concrete must have felt divine.

It was hiding on the edge of the grass before I surprised it.

Most likely a Grass Skink, Lampropholis delicata (ID source, Wildlife of Greater Brisbane).

Most likely a Cuckoo Wasp (ID source - Wildlife of Greater Brisbane). I've seen this wasp several times checking out the holes in the bricks and concrete on the walls. It finally stayed still long enough to have its photo taken.

Still kickin

I wondered if the Assasin Bug nymph that I spotted would survive, particularly after removing the sorghum it was sitting on and feeding it to the chooks. Well, it may not be the same one but at least one adult is still kickin.

I never thought there was so much variety in grasshoppers, but here is yet another colour. The poor thing is looking at me perhaps knowing it's about to be fed to the chooks.

My wife tells me this Earwig at the bottom of a bowl of tomatoes I harvested was in the fridge for two days. It seems none the worse for wear.

Every morning and evening this pair of Kookaburras likes to sit on the neighbour's TV aerial and sing, 'This is my spot'.  Hopefully their spot is more plentiful if I reduce the cane toad population so that more lizards can eat and grow.

Big bug hunters of the night

Such a pity that two of the biggest bug hunters of the night are introduced species. It's not a pity that cane toads make great fertiliser!

Overexposed Asian House Gecko

The cane toads are out in force tonight after some rain. Several brave ones attempt crossing the roads into new territory but not all of them make it... I go out a couple of times a month to get a couple of small shopping bags full and stick them in the freezer (for a relatively humane death).  They are quite easy to locate and catch. They generally prefer short grass and like to sit on the edge of hedges / flower beds where they can make a quick escape into greenery. Shining a bright torch light on them temporarily keeps them still. Then all you have to do is pincer grab them behind the brown, bony ridge in line with their eyes and front legs. This way you avoid the poison gland and they usually can't get their feet to touch your hand. Take care not to point their bottoms towards you though. Many empty their bladder in fright!

Bugs in a moment

I haven't had much time lately to do either photography or update my blog. The weather has been very dry so watering the garden of an evening takes quite a long time. The rest of my time is almost entirely devoted to looking after my wife and very cute little daughter. Gwen is now almost 6 weeks old and seems to be growing a centimetre every week! 

This case moth chose the odd position of next to our front door to do a little rapelling. It went up and down the wall 3 times over the course of 2 days before disappearing.

This small beetle decided to visit our house but fearing it was mistaken as to its lodgings I put it outside to continue its travels (can you tell I've been listening to the Lord of the Rings? There is a fantastic BBC adaption for radio on 13 CDs that Renee gave to me a few years ago. Some of the accompanying music is a bit off the planet when trying to create Elvish singing but that is but a small blemish on its high production values.). My mother tells me it is a Christmas beetle that has a tendency to strip trees bare in Darwin.

Another Harlequin bug visiting the Hibiscus against the study wall.

Sunflowers and tomatoes

We've had a good harvest of sunflowers and cherry tomatoes thanks to the chook poo compost. Of course the insects want their fair share, probably about 1/5th to 1/4 of the tomatoes. Still, Renee is having trouble getting through all the tomatoes and is turning them into salsa and relish.

The harvest from one sunflower head

A more grown up hedge grasshopper than the last photo. They absolutely love munching on sunflower leaves.

Queensland Fruit fly female, Bactrocera tryoni (ID source Brisbane Insects and Spiders). She was quite unconcerned with having her photo taken. No doubt she was very focused on laying eggs.

Fruit fly

My attempt at an arty shot of a sunflower head. Can you spot the grasshopper to the right of the flower's centre and another insect hiding behind the petals in the top right?

Garden predators

We are getting fabulous harvests from our vege patch, with special thanks to our patrollers. We have numerous spiders, wasps and now I spotted an assassin bug!

Unidentified spider on south facing wall

St Andrew's Cross spider with one grasshopper already wrapped and another just caught.

Part of our chooks laying mash is sorghum seeds and we've had a few plants spring up from chook compost. The maturing seeds provide great camoflage for an Assassin Bug, Pristhesancus plagipennis (ID source, OzAnimals). I will be interested to see if this nymph survives to adulthood.
