Crayfish at Chalfont St Giles - we thought this was a natural white claw but, sadly, experts suggest it is not

Signal Crayfish - (an invader)

 Peacock Butterfly

Painted Lady Butterfly

Comma Butterfly

           Saw-wort plant near The Greyhound - Chalfont St Peter

Japanese Knotweed - a prolific invader requiring specialist removal: do not touch

Himalayan Balsam an invasive non native species rampant in parts of Kent, some outbreaks in the Chilterns.  Please let MRA know if you spot it on the Misbourne

Orange Balsam or Jewel Weed - another invasive non-native species but not as harmful as others  ........ and very attractive in small doses!    Prolific on the Misbourne but easy to pull up: try not to let ripe flowers fall on the ground.
