Mass spider web in Texas

We really don’t mean to pick on our arachnophobes. Personally, we love spiders. Harry, our own tarantula, is a beloved part of the Museum and we respect the spider’s amazing place in the food chain (especially considering all the trouble they seem to have from wasps here and here). Creepy as some people find them, they do some amazing things.

We showed you amazing video of a spider migration a while back. This time it’s a mass web, created by a group of spiders in Rowlett, Texas. ABC affiliate, WFAA, reported Thousands of spiders have spun a massive communal web at Rowlett’s Lakeside Park South. As this video shows, the trees are literally draped in webs spun by spiders who have banded together to take advantage of all of the insect life in the region.

Spiders are normally pretty solitary creatures. But under certain conditions they will spin these amazing communal webs which blanket an area. Wired had a report in 2010 about an amazing 4-acre web that occurred in a Baltimore, Maryland water treatment plant. The original report was written by Albert Greene, Jonathan A. Coddington, Nancy L. Breisch, Dana M. De Roche, and Benedict B. Pagac Jr. for the Entomological Society of America. It contains amazing photographs and detailed data of the infestation.

This is nature at its most amazing!

Spider zombies

A while back we told you about the tarantula hawk, the most painful wasp in the world, that hunts tarantulas. Apparently spiders and wasps have a rivalry as big as cats and dogs because here is another spider-hunting wasp, but this one is just weird!

Japanese scientists reported in the Journal of Experimental Biology have observed that the wasp known as the reclinervellus nielseni somehow manipulates a spider to build a special web for its young. In return for this kindness the spider is devoured by the young as they come of age. Here is disturbing video of what happens.

No one is sure how the wasp and its young manipulate the spider. Perhaps it injects a hormone that confuses the spider’s normal behavior. If you’d like to dig into the the scientific data is available.

In my experiments with people I do influence minds, but it’s nothing at all like this! Some of the things that happen in the animal kingdom, particularly with insects, is just plain unpleasant! I’m starting to actually feel sorry for spiders. The wasps are giving them a really hard time.
