It’s spring and a naturalist’s thoughts turn to …

… snails, actually.

After the record rains last week (in 24 hours Lismore 139 mm; my back deck 103 mm – although the absolute record for my back deck is 187 mm in 24 hours a couple of years ago; and anecdotally for Ballina, because the automatic weather station broke, over 200 mm), there’s a certain something in the air. Looking for birds last week at the Wilson Nature Reserve in Lismore, I stumbled across this land snail shell …

Native plant lists for Bungabee and Bentley areas

When revegetating land, it’s helpful to know what was originally in the area and what seed banks are likely to be in the soil once you get rid of the lantana and other weeds. These are the plants that are mostly likely to survive if you plant them or allow the seedlings that pop up on their own to mature. Doing a condensed version of the TAFE bush regeneration course focusing on botany rather than such things as fence construction or chainsaw use, thanks to a government grant, made me aware of ways to do this.

I managed to get hold of a couple of lists via National Parks. They were done by Alan Roberts and Rob Kooyman. They are a bit out of date, but should give an idea of what’s living in the McKellar Ranges at the Boundary Creek (Bentley) and Bungabee State Forest areas. Just ignore the pencil scratchings – they are my notes. The ‘M’ means I’ve found them on my property.

There’s a hole in the paddock, dear Lise, dear Lise

… and it’s because new fencing is going in. Our neighbours dug some post holes and inadvertently performed a small wildlife survey via these ‘pit traps’. Here’s the very common striped marsh frog (Limnodynastes peroni) …

The rise and fall of the red phallus fungus

A couple of posts ago, I reported on the fruiting body of a stinkhorn fungus, Phallus rubicunda. I promised Denis I’d keep an eye out for the development of more, and as luck would have it another one popped out a few days later.

I took a photo a day at around 9 a.m. every morning from beginning to end. Sorry, folks, that’s 27 photos, but it gives a good idea of the “life cycle” of the fruiting body.

A Tramp in the Woods posted a series of photos a couple of days ago on his Phallus impudica, from the Forest of Dean in the UK. There I found out that the “egg” is commonly called (in the UK) a “witch’s egg”. He also has nice photos of flies feasting on the spores, attracted by the disgusting smell. It’s the middle of summer in the UK, but the middle of winter here, so “no flies on us”, as we say.

The witch’s egg above the old fruiting body splits and the fruiting body starts to emerge …

Micro monster … and the kitchen sink

Not the best of backgrounds, but I takes ’em as I finds ’em … it’s a house centipede (Allothereua maculata) in my kitchen sink. I’ve been enjoying David Attenborough’s documentary series, Micro monsters, hence the association. It is not an insect, but a chilopod.

House centipede, Allothereua maculata

House centipede, Allothereua maculata

Wikipedia says, among other things:

The body of Allothereua maculata is made up of 15 segments and bears 15 pairs of long legs. The body is pale brown with dark markings, and grows to 20-25 millimetres (0.8-1.0 in) long. It bears one pair of antennae on the head and a similarly long pair of caudal appendages at the tail end.

The Atlas of Living Australia says:

Description: Medium-sized centipede with extremely long legs and antennae, and compound eyes. Runs very fast and easily drops legs to avoid capture.

Biology: Active at night. Often found under rocks and in litter. Prefers humid, moist areas. A free-ranging predator of ground-dwelling insects. Prey captured by ensnaring in the long legs. Prey consists of smaller ground-dwelling insects and spiders.

Habitat: Bushland areas in southern Australia but may also be found in gardens [and kitchen sinks].

Native status: Native to Australia.

Maximum size (cm): 3.

Diet: Carnivore.

Danger rating: Harmless [to people].

Colours: Blue, grey, yellow.

Distribution: Southern Australia.

Habitat types: Terrestrial.

It’s nice to think of it beetling around (centipeding around?) the place at night cleaning up other insects, in company with larger spiders that munch up cockroaches. My very own cleaning service!
