Sago Palm with Dome Spider Colony

Description:

This Sago Palm (Cycas revoluta), locally known as Oliba, has been adopted as a host plant by a Dome Spider colony (a series of inter-connecting webs). Spiders are not usually considered to be social animals, but the Dome Spider, Cyrtophora cicatrosa Stoliczka, 1869 seems to have developed a life style which is not truly social like ants or honey bees, but appears to have some elements of social behaviour.

Habitat:

The Sago Palm is growing in our front yard. We planted it almost 20 years ago. The Dome Spider Colony has been developing on the palm for a few years now (not sure exactly how long),
