I have spent thousands of hours walking and working in Mt Gravatt Conservation Reserve and I am still seeing things I have never noticed before. The misty mornings air this morning showed dozens of small tent spider webs in communities in the shrubs. The moisture on the webs this morning made for great photography. When I just checked this afternoon these webs are all but invisible.

I could not find any spiders to photograph however these webs are almost certainly made by Dome Tent Spiders Cyrtophora moluccensis which I have found in the Reserve. This larger web shows the amazing structure with a collection of something, possibly eggs, at the peak.

A close up photo shows the neat matrix of thread and the tension cables holding the shape just like a circus bigtop.

We also found this huge beautifully made web, of the Garden Orb Weaver Eriophora transmarina, stretched out between two trees. Another Garden Orb web had stretched right across the track earlier in the week but without the dew droplets it was virtually invisible and didn’t survive as I walked straight into it.

Garden Orb Weaver females build these huge webs as night and usually consume them again in the morning before hiding in a retreat of leaves and twigs. So it was a bit of a surprise to not only find the web still in place this afternoon but also find the owner sitting in the centre. The web had also caught dozens of flying ants during the day.

Another first for me is finding a large number of these webs on the ground which must be there everyday but only noticeable with the heavy dew. These webs are very fine with multiple layers which makes them look like very fine muslin fabric.

I was not able to get a photo of the tiny spiders living in these webs as they quickly disappeared into the hole built into each web.
Any ideas on what spider species makes these fascinating webs?

Thank you, Michael – I enjoyed this post on the spiders of Mt Gravatt. It is so much easier to take the information in than having to look up a book.

Good call Julie-Anne … It certainly seems to be a wolf spider web. Now I just have to find out what species. Interesting.
