Bumblebees paranoid after close run-in with camouflaged spiders.
Hidden and visible spiders were equally successful at catching the insects, but bees that had been caught by a camouflaged spider slowed down their inspection flights. This lost them time, but meant they were more likely to spot any hidden spiders in the future.

In contrast to bees that had been caught by more conspicuous spiders, those bees that had been caught by hidden spiders several times on a previous day were also "jumpy", behaving as if they saw spiders where there were none and rejecting safe foraging opportunities.
