Fuligo septica

I found this is the back yard early in the morning  after rain the previous day. I guessed it was some type of fungus, turns out to be a species of plasmoidal slime mold called Fuligo septica, commonly known as scrambled egg slime or dogs vomit slime mold!

Dogs vomit slime mould. Slime molds are just a collection of amoeba yet they can move and coperate as if they are a single organism with awareness and intent.

Ptilonorhynchus violaceus

The family spent the long weekend at Wombeyan Caves.  They are a group of a few hundred limestone caves set in the Wombeyan Karst Conservation Reserve located about 70Km west of Mittagong. It’s a remote location, there’s a lot of wildlife in the area, we saw a few  different species of kangaroo and a lot of birds. On of them was the Satin Bowerbird. I noticed one loitering around under the camp table during the day, one of our friends we were with identified it. As usual a new one for me. The one near the table was a male, all black with a brilliant blue sheen. I’d noticed a group of dusky green birds cavorting around in the early morning, it turns out they were the females.

Telopia speciosissima

“A magnificent flower long valued for its exceptional beauty” NPOS p. 104

Everyone knows the waratah, it’s big, voluminous and deep red in colour, it can’t be missed or mistaken for anything else. The Waratah is the state flower of NSW and narrowly missed out on being chosen as Australia’s national flower. Golden Wattle only became the official national flower in 1988!

The botanist R.T. Baker was a vocal advocate of the waratah arguing that it alone was unique to Australia, whereas, “in the wattle, Australia has not a monopoly like the waratah, for Africa has over one hundred native wattles, and it also occurs in America, East and West Indies and the Islands.”

We’re just coming out of what felt like a freezing cold winter, it seemed like it was bitter and dark for so long. But when it comes to accuracy human skin and brain cells are really terrible at remembering and comparing the weather. Lucky for us we have the data!

Cold and wet at the Mt Tomah botanical gardens

The BOM have updated their long term climate data again. This time we’re in for a treat, we have updates to temperature, sea level and rainfall. Looking at the maximum and minimum monthly temperature averages we have indeed had some cold months. The July average minimum of 8C is the coldest since 2002 when it was 7.9C, and looking back 30 years only 1995 was colder. The mean maximum for July was cool but many years have been cooler over the past 30 years. 2013 and 2014 were quite warm by comparison though, maybe that’s why it felt cold this year. As we’ve only got up to July we can’t compare moving averages yet. For sea levels the short term averages actually show a drop in 2014. The 5yr and above moving averages still show an unmistakable upward trend. Rainfall averages are up, I don’t recall it being particularly wet though, so much for memory.

For fathers day day this year the family took a trip back to Muogamarra Nature Reserve. Muogamarra is located about an hour north of Sydney just off the old Pacific highway past Cowan. Visiting is a bit of a treat as the reserve is only open to the public for 6 weeks per year. It’s closed at other times to protect sensitive natural and cultural heritage areas. It rained a bit on the way up but by the time we got there it had cleared. much better than last year. We opted to do the point loop trail. Even though we’d done it before it was the best suited for the time we had. Also one of the Nation Parks and Wildlife ladies said that the wildflowers were especially stunning this year and could not be missed! The point loop is an easy 2km loop with a lookout over the Hawkesbury half  way along. The flowers didn’t disappoint, there were seas of yellow bush peas and pink wax flowers. Also a stunning Waratah by the side of the trail, a much better specimen than the one we saw last year.

Perga dorsalis

First up it’s not a caterpillar, it totally looks like one but it’s not! It took a bit of searching to find it’s actually a Steel Blue Sawfly Larvae. Sawflys are large flying insects that are closely related to wasps. Caterpillars on the other hand are the larvae of butterflies and moths. The Steel Blue Sawfly Larvae is commonly known as a “spitfire” or “spitfire caterpillar”.

Cladia retipora

A few months ago I took the boys for a ride on the center track in Ku-ring-gai National Park. We all had a great time on the way out and a good play on a large sandstone pavement that crosses the path. They were pretty tired by then, the trip back wasn’t as happy! Even though it’s quite close to the local bush there were many plants that I’ve not seen in Garigal. I found something that was completely unfamiliar, have a look at the photo:

Boronia ledifolia

“The hardiest and also the earliest flowering of the local species” – NPOS p.116

Tom was the only one that had been home all Sunday, by late afternoon he had a bad case of cabin fever and demanded to go on a bushwalk, and one he’d never been on before. We took a path that joins the usual route, but past where we normally finish, then ended up doing the river loop in reverse. A few different wild flowers were in bloom, it really felt like the start of spring. I took pictures of these small purple flowers, I had a hunch they were a species of Boronia and I was right. Boronia is another one of those plants that everyone seems to be familiar with except me. This particular one is a Boronia ledifolia, commonly known as Sydney Boronia. It’s a common plant, abundant in heath and woodland and also the earliest flowering of the local Boronias. The plant itself is small only growing to 1m in height. it’s flowers are four petalled and a sticking pink in colour, approximately 4cm across. Leaves are thin with a waxy shine, deep green in colour with pots and recurved margins.

It happens every year around this time, this year it was yesterday, August 13th. They were in the Banksia out the back but had gone by the time I got the camera. They’re usually just here for a just one day per year, I’ve not been able to find any information on their migration habits, or even if they migrate at all. But where do they go for the rest of the year! Here they were last year.
