.林至鴻-欄杆上的寶石 (The Gem on the Banister)

欄杆上發現的藍翠蛛，旁邊還出現另外3種蜘蛛。步道欄杆上容易有蠅虎科的蜘蛛出現，可能是因為上面障礙物少，方便獵食。加上常觀察到有小蟲停留，食物充足。觀察地方旁邊有許多蒼蠅聚集，可能是造成那邊蜘蛛特別多的原因。

I found this Siler cupreus spider on the banister alongside 3 other spider species.  The banister on the walkway usually attracts jumping spiders (Salticus), probably due to the banister having no obstacles and is an easy place to hunt for prey. Furthermore, bugs are frequently seen landing on the banister, a good source of food for the spider.  I observed that a lot of flies were gathering nearby, this is probably why there is a large spider population there.
