The bird dropping spider (Celaenia excavata) derives its name from mimicking bird droppings to avoid predators, mainly birds. However, there are other species of spider that resemble bird droppings, for example species of Mastophora (a bolas spider). The males are much smaller than the females, about 2.5 mm as opposed to 12 mm. The females have up to 13 egg sacs, with about 200 eggs each, strung together with strong threads. Their toxicity is unknown, but may be able to cause mild illness in humans. The bird dropping spider stays motionless on its web during the day, only hunting for prey at night. It hangs down from a single silk thread and releases a pheromone which mimics the sex smells released by female moths. When a moth comes near the spider will capture it with their powerful front legs. They can be found in Australia, mainly along the eastern and southern coasts.

Hello there, I am sending you some photos of a spider I found in my veggie garden yesterday. Sadly my daughter sprayed him before I could get the camera, so the chap is dong a 'dying swan' act whilst being photographed. Sorry, as I know you spider people do not kill them, but to many people it is the only way to deal with them!! We live in Whangarei, Northland, in New Zealand, and I have never seen a spider like this before. It was backed up in a corner of a tomato stake, with some of its legs arranged in a row in what looked like the front of it (but when it moved it became evident it was the back). All I saw at first were the two white 'eyes' looking at me. Then I realised they weren't eyes but two raised bumps with white/yellowish markings on them. Then the legs came out and we both screamed - I ran for the camera and she ran for the spray - she got there first! I cannot find anything similar looking in the website (excuse the pun) on NZ spiders, so I am sending you these photos in the hope you can tell me what it is and why the hell it has suddenly appeared in a place I spend so much time in! Specifically, is it safe, does it jump, where does it hide and how do I get rid of them in my vegetable garden - where I am digging, clipping, weeding and generally getting my hands in the firing line of disturbing any creepy crawly. I hope the photos are clear enough, and look forward to hearing from you. Cheers, Sandre

I found this spider on my daughter's play set. We live in south east Texas and I have never seen on of these before. Is there any way you could tell me what it is? Thanks, Lisa

Hi, Can someone please identify the egg cases in the attached photos. Sorry the close up is blurry, macro wasn’t working. However, the ruler will give an idea of scale. I encountered these on acacia brachybotrya. Sticky web. If the cases had been white, I would have said ‘red back’. I have googled heaps but got nowhere. Many thanks, Ann.

To Whom It May Concern, I recently took some photos of a spider, and I particularly want to indetify  them because I wish to upload them to the free enyclopedia, Wikipedia with a
correct identification. There are two spider photos sets attached Thanks, and I think your website is brilliant.  Sincerely, Peter Firus (Click for larger views)
