Ogre Faced Spiders





A spider with remarkable web fishing skills is the Ogre faced spider โ€“ shown here is the Hong Kong species ๐˜ˆ๐˜ด๐˜ช๐˜ข๐˜ฏ๐˜ฐ๐˜ฑ๐˜ช๐˜ด ๐˜ป๐˜ฉ๐˜ถ๐˜ข๐˜ฏ๐˜จ๐˜ฉ๐˜ข๐˜ฐ๐˜บ๐˜ถ๐˜ฏ๐˜ช.


I was again lucky to find this spider thanks to a tip-off from a friend, and I rushed to see him just as dusk was falling. The male spider was resting on some railings โ€“ they are nocturnal spiders and usually found high in trees. You can tell it is a male from the size of the pedipalps.





Their resting pose usually involves them placing each set of two legs together so that they look like they only have 4 legs.


These legs actually have nerve-based receptors that allow them to detect soundwaves, and two of their eight eyes are particularly large to enable them to effectively hunt in the dark, which gives them a somewhat fearsome appearance, hence the name Ogre faced spider.





Ogre-faced spiders spin a web that stretches between their forelegs. They hang upside down (like this spider is doing in the picture) and then hold the web ready. When they see or โ€˜hearโ€™ an insect approaching they then scoop the insect into the web they are holding โ€“ just like a fisherman casting a net.





Sadly, as it was not nighttime, I did not see him in action but this is another amazing example of the phenomenal diversity we have amongst the Hong Kong arthropods.
