The best easterly low for many years, rain pouring down and soaking in to the subsoil, it was sorely needed, the bush and wetlands will be loving it, over ninety millimetres last night and today. Not much chance of outings for a while but good weather to get the next post ready, a few oddments will fill the bill. The warm weather before the rain saw the new season’s sand wasps busy excavating breeding burrows in the sandy soil of the garden.
They are interesting to watch, they dig with their front legs, then lift their abdomens and flick the spoil backwards out of the way. From time to time they also scatter the build up, possibly to disguise their operations. This burrow was close to an ants’ nest and occasionally an ant would go into the burrow to check it out. The wasp wasn’t too keen on this and hovered just above until the ant vacated the premises. In the photo the rapidly beating wings are a barely visible blur despite a very fast shutter speed, 1/2000 sec.
The Tau Emerald, is a very common dragonfly, the Australian Emerald less so around home, but one did appear recently and settled quietly for a photograph. The Tau has bronze coloured pterostigma and leading edge wing veins, the Australian has black, seen in the image. The yellow tail tip in the Australian is also smaller than in the Tau.
An attractive small moth settled on a window, one that I hadn’t seen before and I thought I may have something special. Alas no, it has world wide distribution and the caterpillar is a pest in stored grain. it is a Pyralid,
A small dark object on the brick wall caught my eye and closer inspection revealed a bagworm, larva of a moth in the Psychid family, commonly known as bagworms and case moths. Their shelters come in a multitude of shapes and textures, I hadn’t seen one quite like this before.
