flying insect with long dangling legs
The researchers perform their experiments by encouraging the bees to fly in an outdoor wind tunnel using an incentive of aromatic oils. An analysis of one such spider shows it uses its legs to pick up the sound of flying insects, before throwing a net-like web over the unsuspecting animal. or. Not aggressive: Aggressive. flies).

St Mark’s flies only have a very short life span as adults (i.e. Around the beginning of May, you're very likely to see groups of fairly large, black flies with dangly legs just hanging around in the air. Unlike airplanes, leaving their landing gear down makes bees fly faster. Dangling upside down from its simple web, the spider dives forward and casts a pre-spun net, held between its four front legs, over prey passing below, says Jay Stafstrom, also at Cornell.
