Life and death in the monsoon

The arrival of wet season rains is a time of renewal – the wetlands are replenished, the frogs breed and provide food for many other creatures. We find the sound and smell of the rain itself as well as the deafening cacophony of frog calls exciting ……. last night we had a look in the pond adjacent to our verandah.
A water spider, Pisauridae species of the genus Dolomedes, had captured a Graceful Tree-frog (Litoria gracilenta), one of many calling around the pond.  According to Arachne.org.au “As Australian Pisaurids are being revised by Robert Raven at Queensland Museum, until this review is complete it will be difficult to correctly identify many Dolomedes species”

In the car-port a white-lipped green tree-frog (Litoria infrafrenata) was hanging onto our vehicle while numerous sedge frogs (Litoria bicolour, Litoria fallax)   called and jumped around the house;  several had to be taken outside again after they found their way inside.

This morning we had a look for the remains of the spider’s meal;  it was dragged up onto one of the rocks surrounding the pool –  a somewhat gruesome sight softened by the flower petal decoration;  exactly as found.

And so the circle of life continues –  frog eggs (probably L. gracilenta) on the water below the frog corpse.

Swimming with Spiders

 Recently, while cooling off in our natural swimming pond, I noticed a spider on the water’s edge.  When I attempted to get close for a better look it ran away on the water and then went under the surface where it remained quite stationary on the tiles for several minutes.  I returned to the pool several times with the camera before I managed to get this photo but unfortunately from that angle I couldn’t get a good view of the eye arrangement.

Our attempts at identification were unconfirmed until we just happened to have a spider enthusiast visit us a couple of days ago.  Although unable to identify the species from the photo Greg was confident that the spider belonged to Dolomedes, a genus in the family Pisauridae, which is the nursery-web or water spider family.  The female nursery-web spider carries her egg sac Continue reading
