Henk Lammers in Hupsel village in the Netherlands made the video.
This video from Britain is called Grayling Butterflies, Hipparchia semele.
This summer, graylings are the most common butterflies: hundreds were seen.
About dragonflies, they write:
Not only for birds the water tank below the tower is useful. For dragonflies it is interesting, because between 1 and 11 July here almost daily ruddy darters metamorphosed from larva to adult. Based on the number of counted and collected larva skins at least 48 individuals emerged from the shallow water. Special, they all came from such a small pond! Reproduction of dragonflies on Rottumerplaat is known from only a few species. On 5 and 6 July, a strong southerly winds brought large numbers of dragonflies to the island. This were mainly various types of darters, including the nationally rare yellow-winged darter, of which one female was observed. We have also seen an emperor dragonfly a few times.

Scarce Tortoiseshell Feeds on Oak Sap ヒオドシチョウがミズナラ樹液を吸汁

A Scarce Tortoiseshell (aka Yellow-legged Tortoiseshell; Nymphalis xanthomelas japonica, family Nymphalidae) feeding on the fermenting sap of an oak tree (Quercus crispula, family Fagaceae). October 2013 in Japan.

This week a butterfly species entered our country which had never been seen before in the Netherlands: the scarce tortoiseshell. This involves dozens of individuals. This species was initially unnoticed because it is very similar to another one: the large tortoiseshell. An expert from the Butterfly Foundation discovered that many sightings of large tortoiseshells reported since late last week were incorrect. It was in all cases the scarce tortoiseshell.
Usually, this species, new for the Netherlands, lives much further to the east.

Imagine a world without bees..
Imidacloprid is the most widely used insecticide in the world and Bayer´s best-selling pesticide (2009 sales: €606 million). The substance is often used as seed-dressing, especially for maize, sunflower and rapeseed. The beginning of the marketing of imidacloprid coincided with the occurrence of large bee deaths, first in France, later on also in many other European countries, Canada, the US and Brazil.
After huge bee mortality in Germany in 2008 which was shown to be caused by neonicotinoid pesticides the Coalition against Bayer Dangers accused the Bayer management of downplaying the risks of imidacloprid, submitting deficient studies to authorities and thereby accepting huge losses of honey bees in many parts of the world. At the same time, German authorities imposed a ban on the use of imidacloprid and its successor product, clothianidin, on maize. Italy and Slovenia imposed a similar ban.
In France imidacloprid has been banned as a seed dressing for sunflowers (since 1999) and maize (since 2004). In 2003 the Comité Scientifique et Technique, convened by the French government, declared that the treatment of seeds with imidacloprid leads to “significant risks for bees”. The consumption of contaminated pollen can cause an increased mortality of care-taking-bees. When individual bees were exposed to sublethal doses their foraging activity decreased and they became disorientated, which researchers concluded “can in the course of time damage the entire colony”. Clothianidin was never approved in France.

Declines in insectivorous birds are associated with high neonicotinoid concentrations

Recent studies have shown that neonicotinoid insecticides have adverse effects on non-target invertebrate species1, 2, 3, 4, 5, 6. Invertebrates constitute a substantial part of the diet of many bird species during the breeding season and are indispensable for raising offspring7.
We investigated the hypothesis that the most widely used neonicotinoid insecticide, imidacloprid,
a Bayer corporation product
has a negative impact on insectivorous bird populations. Here we show that, in the Netherlands, local population trends were significantly more negative in areas with higher surface-water concentrations of imidacloprid. At imidacloprid concentrations of more than 20 nanograms per litre, bird populations tended to decline by 3.5 per cent on average annually.
Additional analyses revealed that this spatial pattern of decline appeared only after the introduction of imidacloprid to the Netherlands, in the mid-1990s. We further show that the recent negative relationship remains after correcting for spatial differences in land-use changes that are known to affect bird populations in farmland. Our results suggest that the impact of neonicotinoids on the natural environment is even more substantial than has recently been reported and is reminiscent of the effects of persistent insecticides in the past. Future legislation should take into account the potential cascading effects of neonicotinoids on ecosystems.
