Look – and listen - out for Green Hairstreaks

Only very few sightings of this beautiful butterfly were recorded in Rother last year. Does this mean this nationally widespread butterfly is scarce in our region or is
it simply under-recorded? Let’s try and find out! This year we are alerting everyone to look out for this elusive species, which uses the widest variety of food plants of all British butterflies and is – at least theoretically – found in a wide range of habitats where shrubs are present.

Britain’s only green butterfly pupates in August and hibernates as chrysalis. In order to keep warm and protected over winter, it has evolved an extraordinary and unique "trick": The chrysalis emits loud squeaks, audible to the human hear, to attract ants and entice them to drag the chrysalis into their nest.

  1. I saw one today (06/06/2010) at Fishponds meadow, Hastings Country Park TQ843108. The meadow is a patch of rough unimproved grassland, mown once a year.
