Posts Tagged ‘spider silk’

The more I watch spiders, the more I am fascinated by them. I used to think that spiders extruded only a single kind of silk, but I have learned that many spiders have multiple spinneret glands that are used for producing different kinds of silk.

One of the most amazing kinds of silk is known as aciniform silk, according to Wikipedia, which is used to wrap up and immobilize prey. This silk looks like a long gauze bandage as it is extruded by the spider.

Last month, I watched as a large Black and Yellow Garden Orbweaver spider(Argiope aurantia) wrapped up a recently captured bee. I was amazed at how quickly it accomplished the mission, spinning the prey as it wound multiple layers of silk around it. Here are a couple of shot I took that show the spinnerets in action.

I loved the reaction of one of my friend to the first photo. He imagined the bee protesting being wrapped in bandages saying, “Hey, you’re not my doctor!”
