Long-horned Orb-weaver Spider (Macracantha arcuata) As members of the orb-weaver family of spiders, these amazing creatures build the typical circular web of their cousins across pathways so you can walk into them in the dark. The purpose of the disproportionately long body horns however remains a mystery. This is one of the larger individuals I have come across; each horn is about 45mm in length. by Sinobug (itchydogimages) on Flickr. Pu’er, Yunnan, China

Sixty new species found in Suriname – in pictures

Amazing! Credit: Trond Larsen/Conservation International Many planthopper species exude waxy secretions from the abdomen, and these sometimes form long strands, such as can be seen here. The long waxy strands may provide protection from predators - fooling them into attacking the wrong part of the insect. The wax breaks off while the insect jumps to safety. The juvenile planthopper in this photo is only about 5mm long, and was exceedingly difficult to photograph!
