Some were horrified at the prospect of eating insects, though others enjoyed the challenge at the Grassmarket in Edinburgh.
One woman described her crickets as "wafery and tasteless", and her locusts as "quite creamy on the inside and very insecty". "It's a case of mind over matter," she said.
It is thought insects may be a cheap, sustainable and efficient way to feed the rising world population. More than two billion people worldwide supplement their diet with insects, which contain four times as much protein as the same weight as chicken, and fewer calories.
The event was sponsored by the pest control firm Rentokil.
