My smart little orb weaver

A new spider season. As summer starts, the webs are getting bigger, and there are lots of them. Last season there were few orb weavers around. After a wet winter this year, there are plenty. Three of the orb weavers I am checking every night are three different species. I have become extremely fond of the little spider in this blog, who I've watched grow from a speck to near her full size, a body length of about 10 mm.

Intelligentsia is a clever little spider. She built her web across the door into my Garret, the studio where I write. I have 'trained' orb weavers before - moved the main structural lines which were in the wrong place a few times, and the spider seems to get the idea. I did the same with Intelligentsia. For a month or so now, she has built her web with a curved 'doorway' for me just high enough to go in and out with ease. Unfortunately, husband Damian forgot to duck last week and ruined Intelligentsia's web. Fortunately, as he bumbled into her real estate during the day, she was safely tucked away in her retreat.

Intelligentsia has the bumps on her abdomen, front and rear, typical of her species, Eriophora pustulosa. Her underside has the black patch which also distinguishes the species. This is the view I get as I leave the Garret. 


Intelligentsia comes out each night, repairs her web (or rebuilds it if some silly man has forgotten to duck). She lives the usual active life of a spider, including catching, killing and and devouring insects.


During the day, Intelligentsia retreats to a patch of old web from a long-gone cobweb spider in a gap in the verandah roof. One leg is always in touch with her orb web, just in case dinner arrives early.


I'll introduce the other two orb weavers in the next blog. And keep you informed on Intelligentsia's life.
