It's a photo that should delight the British.
The six-year-old Princess Charlotte gazes intently at a butterfly, which she holds in both hands.
An admiral butterfly.
On Saturday, Charlotte's parents, Prince William and Duchess Kate, published the motif via Instagram and Twitter.
And combined it with a message to their own compatriots.
The people should take part in an action that runs until Sunday: the large counting of butterflies.
It had started on July 16.
Participants can use the app to report when they see butterflies.
The royal couple emphasized in a comment that butterflies are not just beautiful creatures.
"Butterflies are vital parts of the ecosystem - as pollinators and as parts of the food chain." It is hoped that their numbers have increased compared to the previous year.
In addition, the couple spread the catchphrase »savebutterflies« - »Save butterflies«.
Environmentalists fear, however, that the weather could have had a negative impact on stocks.
A warm April was followed by a cold snap in May.
Butterflies don't like that.
