Brain teasers are a fun way of testing a person's puzzle-thinking skills all while remaining thoroughly entertaining.
A new tricky brain teaser challenges people to find a butterfly hidden amongst the colourful summer flowers.
Allegedly only those with sharp eyesight can spot the orange butterfly, which is cleverly camouflaged amongst flowers of a similar colour.
The puzzle, which was created online by plant specialists Hopes Grove Nurseries, determines the sharpness of your sight if you can spot the insect within the 15-second timeframe.
Morris Hankinson, Director of Hopes Grove Nurseries, said: "We wanted to create this brainteaser as a way to mark World Environment Day."
They went on: "With the record time of fifteen seconds to complete this quiz, we're looking forward to seeing who can beat that!
"Let us know and good luck!"
Since the time limit is so short, we advise people to quickly scan the image from top to bottom.
We'll give you a small hint... The orange butterfly is perched upon some orange and yellow flowers. Have you found it yet?
