Spider and Wasp Fossil
What you are seeing here is a small piece of natural history frozen in time. During the early Cretaceous period (between 97 and 100 million years ago), a juvenile orb-weaving spider (Geratonephila burmanica) was on its way down to a parasitic wasp (Cascoscelio incassus) that had been caught in its web. The wasp belonged to a group that are now known to parasitize spider eggs, so perhaps this wasp became trapped while searching for eggs.
Just as the spider walked up to the wasp, tree resin flowed down and engulfed both the predator and its prey, trapping them in exactly the moment before the spider began its meal. This is the first time such an attack has been preserved in amber, and it gives us a rare glimpse into the ecology of dinosaur-era insects.
What makes this fossil even more amazing is the presence of the web itself trapped in the amber, as well as a second adult male spider of the same species in the same web. This makes this the oldest evidence of social behaviour in spiders, who normally prefer to live alone. Today, male social orb-weaving spiders tend to live on female-constructed webs, where they help capture prey and maintain the web.

The leaf cycle:
During the spring and summer leaves serve as factories where most of the foods necessary for the tree’s growth are manufactured. The process, known as photosynthesis; takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green colour. Along with the green pigment are yellow to orange pigments; carotenes and xanthophyll, however most of the year these colours are masked by great amounts of chlorophyll.
In autumn, because of the changes in daylight hours and changes in temperature the leaves stop photosynthesising and hence the chlorophyll breaks down. The green colour disappears, and the yellow and orange colours become visible. At the same time other chemical changes may occur, which form additional colours through the development of red anthocyanin pigments.
Eventually the tree sheds the leaves to save nutrients and prevent loss of water, the leaves then rot and return to the soil as organic matter.

Fourth Class Gardening Project Jan.-Sep.2012
Ms Maher´s class (with some help from Mr. Ring´s) started the gardening project back in January with the construction of two raised beds. After lots of hard work and plenty of summer rainfall a bumper crop of vegetables (carrots, potatoes and lettuce) has been produced and consumed!! Click here for the photo gallery
