I'd always thought that spiders were exclusively predatory, but it turns out that they can eat pollen and some even feed almost exclusively on bananas (what can I say wikipedia is an adaption). In any case not sure if the pollen stuck to this one was accidental, being used as a hunting "cover" for pollen-feeding prey or it's a little snack for the spider, but I thought it was pretty cool and lead me to do some added reading.
