This video is about male and female brown hairstreak butterflies.
The Dutch Butterfly Foundation reports about the brown hairstreak butterfly, a rare species.
A few years ago, in Steenwijk town, a sports ground was renovated, causing destruction of brown hairstreak biotope.
Pro-butterfly activists complained about this to local authorities. As a result of this, blackthorn bushes, on which the butterflies depend, were planted all over Steenwijk. This enables brown hairstreaks to live at many spots now; making them no longer dependent on one vulnerable area.
This winter, over 1,850 brown hairstreak eggs were found in Steenwijk. A record number.
