Lots of flea beetles are from a photo unrecognizable. Length about 2 mm. Photos 11-10-2012. 
  

The first photo was taken in 2007, the left photo in 2008. Then this was an Asiorestia spec. Because they are very much similar to the Neocrepidodera species the name is changed into Neocrepidodera spec. In the Nederlands there are some similar species: Neocrepidodera ferruginea, Neocrepidodera motschulskii, Neocrepidodera transversa. They are shiny brown beetles, which may very well jump. Length 2 - 3 mm.

It lives on the Evening Primrose. That's the difference with other blue flee beetles. It's also a good jumper. It damages the plant. But the plant will survive. Length 3 - 4 mm. Photos 1-4-2008. 
  

This black flea beetle is found on plants from the borage family (Boraginaceae). Here he is on a leaf of a green alkanet (Pentaglottis sempervirens). The lower part of the legs is yellow-brown, like the lower part of the antenna.
Length about 2, 3 - 2,5 mm. Photos 1-5-2015, 6-5-2015. 
  

The head, legs and the top of its carapace are black , the side is yellowish white. The pronotum is brown. 
It has several food plants. Especially groundsel and ragwort. The larvae develop in the roots of the host plant. The adult beetle overwinters. 
Length about 2 -3 mm. Western and Central Europe. Photos 13-11-2013.
  

These very small beetles live on different grasses. Chaetocnema hortensis is one of the best known species. But there are about 20 in Europe, which are very similar.
Despite that they are so small, they are striking, because they are so shining in the sunlight. On the picture you can see, that the head and pronotum is also punctuated. Length about 2 mm. Photos 29-4-2013. 
   

A Chaetocnema species has an undented pronotum and regular puntuated rows on the elytra. The two bronze-coloured species with regular puntuated rows: the Brassy flea beetle, Chaetocnema concinna (1.8-2.4 mm) and Chaetocnema picipes (1.7-2.3 mm) live on Knotweed and Sorrel. They can't separated from a photo. Jaap Winkelman thanks for the identification and and the information. Photos 16-10-2011.
  

Not quite sure by the resemblance to the Netherlands in very rare Bruchidius cisti. A grey beetle with short elytra. 
This seedbugs lives as larva in the pods of Broom. But it also likes the seedpods of the Golden Rain. The adult beetle feeds on pollen. On this photo it eats a by pear rust affected leaf of a pear tree. 
Native to Europe. But introduced in America and New Zealand. There it is used as an agent of biological pest control against the noxious weed known as Scotch broom (Cytisus scoparius).
Length about 2-3 mm.  Other species in the Netherlands: Bruchidius cisti, Bruchidius varius and an exotic Bruchidius incarnatus.  Photos 16-6-2014. 
       

Small and shiny. Yellow with a green sometimes purple sheen. The rows of dots are even. The head is black. Length 3.5-4.5 mm.
Host plants are among others called spurry (Spergula), Silene and Centaurea.
Europe, Asia Minor. Photo's 18-8-2018.
  

Heather beetle  (Lochmaea suturalis).  Lochmaea suturalis  lives in areas of heath. But you can find it on other plants too. Heather beetles eat the young leaves of the heather. The larvae eat the roots. For the plant, they are harmful. I live near the dunes with heather. It is possible, it is a heather beetle.

Yellow willow beetle  (Lochmaea caprea). The willow leaf beetle lives on willow, poplar and birch. We have a birch in our garden. A yellow willow beetle is also possible. Length: 4 - 6 mm. April - September.
