The good people at Senckenberg Institute will be hosting a symposium in Laos from 12th to 15th November 2012 which will be themed on the spiders of grether Mekong. I expect this to be an educative meetings among arachnologists and spider enthusiasts who are looking at the South East Asian region.
Entrance is free but you have to arrange for your own travel and accomodation. The host, Dr. Peter Jaeger, can be reached at firstname.lastname@example.org if you need his help in securing a place.
From 16th-23rd you can join scientists in a series of workshop and excursion in Tad Itou. This is how the place supposed to look like.
Dorm rate is USD10/night and nice room at USD40.
I will be presenting on spider photography and spiders which might be of medical interest.

This is a rather common spider found around grasses and low shrubs. Their webs are hardly more than 1 foot from the ground, often decorated with stabilimenta. The genus Gea (family Araneidae) is closely related to Argiope (often called St Andrew's Cross) and the more uncommon Neogea. Females can reach up to 11mm which makes them easy to spot and photographed. Sexual dimorphism is not as extreme although males are significantly smaller.
This spider has an extensive range throughout the tropics with records even in India. I often found then in large numbers among long grasses along trails, even nearby human settlements. Approaching one is considered easy as they do not easily startled. At most, the spider will move to the other side of the web in a flash.
So far I found them to be diurnal. They are especially easy to find in the morning following a raining night. The webs will be covered with water droplets, making them visible from quite a distance.
This one was seen moulting during daytime, about 11am or so, in a forest not far from Kuala Lumpur.
Small flying and hopping insects seem to be their main prey. Usually I found plant hoppers being caught and in one incident I saw an Aedes mosquito being devoured.
A contrast in size between sexes can be gauged from the video below.
