Spiders Distribution Map

I decided to construct a ‘Spiders Distribution Map of Brisbane’, and then I find that this is out of my ability. I think at least I can make a ‘Spiders Distribution Map in my Backyard’. I constructed the map as below. And I find that its application value will not be less than the Distribution Map of Brisbane. 


My House


























My house is one of the normal suburban houses on a block of 600 square meters of land in Brisbane, Australia. With some adjustments, the map can apply to your house as well. It help you to locate the spiders that you want to find and also help to identify the spider.

The best time to watch spiders is after dark. Remember NOT to disturb the spider because they will bite, some even can kill. Find out which spiders in your area are dangerous and try to avoid them. In general most of the spiders are harmless and they will not attack human unless this is the last thing they can do. And more important, if you disturb them, they will move away and you will not see them there next time.

Spiders, unlike insects, they will not run or fly away when you discover them. Most of the time they are just motionless, on their webs or on their site, waiting for the prey. What you need is patience, remember where they are, come back to visit them from time to time, and record what they are doing. If you are lucky enough and patient enough, you will see how they catch their prey, how they build their web and their egg sac, how they courtship and mate, how the young spiders hatch from the egg sac and how they moult.
