Pointy Orbweaver
(Araneus acuminatus) female

Plants, birds, spiders, insects and more. A delightful time was had at Ravensbourne National Park by our members on our February outing. Quite a number of invertebrates were recorded. The first two images here are of a female and male Pointy Orbweaver (Araneus acuminatus). You can gauge by the size of the leaves in the second pic that they are very small and easily overlooked. Like many orbweavers the female will build her web at night and pack it up in the morning, then find a retreat in which to shelter during the day. Sometimes they can be found in daylight head down on their web. The male is almost half the size of his mate. Their abdominal patterns vary.

Dotty Lynx Spider
(Oxyopes punctatus)

Another tiny spider (approx. 7 mm) is this Dotty Lynx Spider (Oxyopes punctatus). Like its name, Lynx, suggests it is an ambush spider rather than a web-builder. Again colouring and patterns can be variable. They have been found from Cape York to Brisbane.
