All Wrapped Up

Jul 23, 2013

Just call it a missed opportunity.

Catmint (genus Nepeta) draws scores of insects, from honey bees to leafcutter bees to European wool carder bees.

It also draws spiders.

We usually see a cellar spider (family Pholcidae) trapping prey in its web.  It inflicts a fatal bite and then wraps it for later consumption.

This cellar spider, however, crawled along a catmint stem to wait for prey. A honey bee buzzed down and began nectaring one of the lavender blossoms. 

It was not aware of the predator. Just as the spider moved toward it, the bee took off.

Later we saw the cellar spider wrapping prey. A closer look revealed it was not a honey bee, a leafcutter bee or a European wool carder bee. 

It was another cellar spider. Sexual cannabalism? Maybe. A very hungry cellar spider inept at catching a bee so it nailed a fellow spider instead?  Perhaps.

At any rate, that was "what's for dinner."
