20180531 Cross country trip of flower spider on a windy day

In the early afternoon I noticed a white “blob” swaying in the wind on a blade of grass.  Upon closer inspection with the telephoto lens it appeared to be a flower (crab) spider, Misumena vatia.

Over the next 45 minutes I watched that spider travel about 3 metres downwind into a bunch of emerging Canada Anemones.   Most of the time I was looking through the Electronic View Finder of the camera, trying to follow and keep focus on that little piece of white bobbing in the strong gusty wind.   I managed to get a few pictures.

In all cases below, the wind is blowing from left to right.   The wind drifts the spun silk downwind towards other blades of grass and seed heads.  Usually there are several filaments blowing it the wind at one time.  They appear to be at least a metre long.  Click on photos to get close-ups.

Then, after a filament connects to something downwind, the spider climbs along it to a new position.

Resting on a seed head …

It went down that blade of grass to hide in ambush on the dandelion flower.   The approaching Syrphid fly didn’t land on the flower — a wise move!!!

Then the spider went up the stem to the seed head and began to splay our filaments of silk….

It then tightened the silk, pulling the seed head towards its destination …

and then it arrived at the next seed head….

There are several filaments connecting this seed head with the target downwind …

This is the only image that I managed to get of the spider “enroute” to the next seed head.

This is where the spider was headed, one of several Canada Anemones about to bloom…

Here it is ready to release some more filaments downwind to tangle in the blades and seedheads of the grasses.

I have to conclude that these spiders only travel downwind this way.  This indicates that the architecture of cobwebs is affected by the wind at the time of construction.

Lots to learn out there.

This is what is happening at high elevations in New Hampshire these days:

  4. Wow, Tom, this is a picture story in a complete set, showing all the hard work this spider did!!! Spinning that web while you captured it all was an amazing feat!! Congrats to you! A very enjoyable story!! Diana

    • Thanks Diana,
      I was very lucky to be in the right spot at the right time — and to notice the spider! It was a very interesting 45 minutes. I went back a week later and saw a crab spider in an ox-eye daisy at the same spot on the Old Still River Road. I think it was the same one.
