When they are young, they have a beautiful green colouring. It changes in  grayish green when they are old. 
You can find this species in birches. In my garden I find them in the bay shrubs near the birch. 
They feed on leaves of trees and bushes such as birch, apple, strawberry. They are no pest in my garden.
The larvae feed on roots.
Europe. In America (Green immigrant leaf weevil) since 1906 (first found in New York)

April - July  

This snout beetle I’ve often seen in June 2008 in the evening in the Goldenrod. When you try to catch it, it prefers to fall down. 
Length: 4 - 6 mm
Sandy soils. Oft along the coast in the dunes.
Western and Central Europe.  April, Mai, June
There are similar snout beetles like species of the family Strophosoma.

Photos below: April 2009

German: Graue Kugelrüßler     

There are a number of similar Sitona species. From a photo it is not possible to determine this sitona. 
It was walking on the terrace under my chair on a sunny day in the autumn. 

German: Blattrandkäfer, Graurüßler

This weevil walked on my arm.
It is a European beetle, which feed on several species of clovers. It is found now also in other parts of the world.
The beetle eat the clover leaves.
The larvae eat the roots.

Length: 4 - 5 mm.

There is written a lot about this pest on the internet, but nothing in Dutch. Particularly in New Zealand it is a pest.
The clover weevil was first identified in New Zealand in 1996. On this site you can read more:  http://www.ceresfarm.co.nz/clover.htm

Loosestrife flower weevil (Nanophyes marmoratus) Subfamily: Nanophyinae. Family Curculionidae
If I see this little snout beetle, my admiration for nature increases. So small and so beautiful. It was walking  around on the leaf. It was difficult to get a good photo.
They are feeding on youngest leaves and flower parts.  Eggs are laid singly into the tips of flower buds. Attacked buds remain closed and often drop to the ground.This year (2008) in my garden especially flowers of purple loosestrife (Lythrum salicaria). In August appears a new generation of beetles. This generation hibernates in the leaf litter. The development from egg to adult snout beetle lasts a month.
 
Measuring 1,5-2 mm !!
This little beetle is  widespread in Europe. But it is also common in America now. In fact I could find more information  on the American sites. There it is used as a biological control agent, for in America purple loosestrife is an invasive weed.

On these photos the weevil eats the pollen. But it seems to be a pest for the strawberry and raspberry plants in Europe.
Beetles eat the leaves. The females lay one egg in the bud, where the larva develops.
The beetle overwinters.

Length 2 - 3 mm

German: Erdbeerblütensteche 

Probably Clay-coloured weevil Otiorhynchus singularis but Otiorhynchus veterator is also possible.

Otiorhynchus singularis is seen as a scourge for raspberry growers. In spring it feeds on buds and shoots of raspberry, but it likes also rhododendron.
The larvae feed on the roots of bush fruit.
The larvae overwinter.
Length 7 - 8 mm
They are distributed worldwide.

German: Braune Lappenrüssler 

Strawberry Root Weevil (Otiorhynchus ovatus) Family Curculionidae

Dark brown to black with red legs and antennae. They can not fly.
The plants you can find the beetle include strawberry, raspberry, rhododendron, grape, and peppermint. 
The white, legless larva feed on the roots of these plants. As they get older, they feed on the leaves ..
Length 5 to 7 mm.

German: Erdbeerwurzelrüsselkäfer , Kleiner Schwarzer Rüsselkäfer French: Le charançon de la racine du fraisier

A black weevil with light spots (light yellow hairs) on the back. 
This weevil can't run and fly. For a beetle it can be quite old. Even a few years. It feeds on leaves of different plant species.
The larvae are white and they are a pest for many plants. In my garden it is not a problem. But in flower pots, it can be a pest. Also on a plant nursery, they are not happy with black vine weevils. The larvae feed on the roots of plants like conifers, rhododendrons, strawberry plants. Also potted plants like fuchsia, Kalanchoë.
A natural pesticide by the pest is a nematode. They eat the larva from the inside.
The larva overwinters.
Length 9 to 11 mm
Native to Europe, but they are also common in North America.

German: Gefurchte Dickmaulrüssler,  Breitmaulrüssler French: L'otiorhynque de la vigne

A family of small snout beetles. They all have the shape of the pictured beetles. 
From a photograph, they are usually very difficult to identify. These weevils may be beetles in the subfamilies Diplapion or Aspidapion.
Perhaps Aspidapion radiolus, because they are found on mallow. These weevils are sitting on comon mallow.

Length 3 - 4 mm
