Casual Night with Arachnids

Casual Night with Arachnids

In two days Science on Google+ will be streaming “Casual Night with Arachnids”. The Hangout On Air will consist of a series of short presentations from spider experts (see http://goo.gl/knJbyX for event post), and we are inviting all of you to watch the live event.There will be several minutes after each talk to answer questions. Please feel free to use the Q & A app or event post to ask questions. Questions can also be submitted to @spiderprofessor on twitter. Please use the hashtag  #arachnids14 . You can also watch the archived event on our youtube channel (http://goo.gl/zjmEfu). Subscribe to the page if you want to keep up on our HOAs.

In preparation for the event, we are sharing this GIF of an Ogre-faced spider (Deinopis subrufa), which is casting a net on a cricket. You can learn more about these net-casting spiders here (http://goo.gl/bWPW3s) and here’s a short video showing an Ogre-faced spider weaving a net and using the net to catch prey (http://goo.gl/QaHU31).

  1. Sanjay Awasthi the spinneret glands located at the tip of the spider abdomen can generate different types of silk, some with very high tensile strength. According to Wiki, “Many webs span gaps between objects which the spider could not cross by crawling. This is done by first producing a fine adhesive thread to drift on a faint breeze across a gap. When it sticks to a surface at the far end, the spider feels the change in the vibration. The spider reels in and tightens the first strand, then carefully walks along it and strengthens it with a second thread. This process is repeated until the thread is strong enough to support the rest of the web.” More: http://en.wikipedia.org/wiki/Spider_web
