Silver-studded blue butterfly, still in November

This 20 July 2013 video, recorded near Uddel in the Veluwe region, is about silver-studded blue butterflies.

Kars Veling of the Dutch Vlinderstichting reports today that on 2 November a silver-studded blue butterfly had been seen. This species had never before been seen so late in the year in the Netherlands.

Because autumn weather so far is mild, also other butterflies were seen later than usually.

California sister butterfly at feeder, video

This video from the USA says about itself:

California Sister Butterfly visits the Feeder, September 29, 2015

The upper surfaces of the wings of Adelpha californica is a dark brown to black. It has two large orange patches near the tip of the forewings and wide postdiscal creamy white bands on both wings. The ventral surfaces of the wings are generally similar but with blue bands along the edges of both wings, as well as blue and orange patterns on the corners near the body. Like other members of the genus, the butterfly is named “sister” for its black and white markings on the forewing that resemble a nun’s habit.

Helping wheatears, butterflies on Texel island

This is a northern wheatear video.

Translated from a 10 September 2015 blog post by warden Jitske Esselaar on Texel island in the Netherlands:

At work for the northern wheatear in the Eierland Dunes

Today, 30 employees of BirdLife in the Netherlands have turfed about 15 slopes in the Eierland Dunes in the northern part of Texel. These are small patches of about 5 x 5 meters, where the vegetation has been removed.

The purpose of this turfing is to bring back bare sand and the removal of high grasses. On the barren sand different plants can germinate again, for example dune pansy and heath dog-violet. This kind of vegetation is important for wheatears looking for food here. The Eierland dunes are an important breeding ground for wheatears. In 2015, no fewer than 30 breeding pairs were counted, this is a great number for this species which has declined sharply!

For three rare Texel butterfly species bare sand patches are important as well. The dark green fritillary, Queen of Spain fritillary and Niobe fritillary lay their eggs on violets.

Small caterpillars of large white butterflies, video

This video shows large white butterfly caterpillars hatching from their eggs. They are only a few minutes old.

They will start feeding on their own, nutritional, eggs. Then, they will eat plants.
