Leaf beetle (Chrysomelidae).
There are many species of the family of leaf beetles. They usually have striking colours. They are almost all herbivores. And therefore often harmful.  

Flea beetle. Subfamily Alticinae. 
Many small leaf beetles are good jumpers. They are recognizable by the muscular hind legs. There are many species.

Alticinae, maybe an Aphtona or Longitarsus-speci. Family Chrysomelidae.

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. Here information. 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.

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.

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.

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.

Not quite sure by the resemblance to the Netherlands in very rare Bruchidius cisti. ( Bruchidius ) 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.

The asparagus beetle has shiny, blue-black elytra with a red border. On the elytra are white spots. Sometimes there is more white, as you see the left photo. The thorax is red. The head, legs and antennae are black. The larvae are brownish gray, olive green and also feed like the beetle on the asparagus. 
They pupate after about three weeks in the soil. There are two generations per year. The roots of the asparagus are not happy eaten. 
Length about 6 mm.

This shiny, bright red beetle likes lilies and other members of the family Liliaceae. But the most damage is caused by the larvae.
The beetle don't taste well for birds. The beetle uses the red colour to warn enemies. The larvae make a protective shield with their own frass.
They overwinter as adults. For several months the females lay eggs on the underside of a leave. The larva pupate in the ground.
Length: 8 -11 mm. Photos 20-8-2012, 13-6-2009

Shiny blue green.
Both the adult beetle as the larva is to be found especially on the birch. Fortunately not in our garden. There were many of these beetles on the leaves of the birch trees in the dunes. Therefore it was not so difficult to identify. It is very similar to other species.
Length: 4,5 - 5,5 mm.

Rietkever  Donacia clavipes Donacia clavipes. Subfamily Donaciinae. Family Chrysomelidae.

One of the few reed beetle species, which can be determined from a photograph. This is because of the following characteristics: No dents in the elytron, yellowish legs and antennae, rather long legs.
Cane Beetles look more like shiny, gold longhorn beetles, than like leaf beetles.
A Donacia has a soft hairy belly. By air between the hairs, they can float on water. You see them mostly along the waterside on marginal plants and floating water plants. This one sat near the pond with no-look-look.
The larvae live under water. They breathe the air
in the channels in the leaf stems of aquatic plants like water lilies.
Length 10 mm.
Late May
- October.

Not in the garden, but in the dunes about 4 km from our house.

The beetle is dull black and elytra and pronotum are coarsely and densely punctured. The beetle in the picture is a female with greatly enlarged abdomen. (Because of he eggs)
The eggs are at the same time with as many as 60 is attached to a leaf or stem. They are protected by the secretion of the beetle.
Galeruca tanaceti feeds on a lot of plants! Namely all kinds of plants from the sunflower family (Compositae or Asteraceae), carnation family (Caryophyllaceae), teasel family (Dipsacaceae), lily family (Liliaceae), mint family (Labiatae or Lamiaceae), knotweed family (Polygonaceae) and nightshade family (Solanaceae).
Length: 6 - 10 mm.

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.

The Viburnum Leaf Beetle lives on different species of Viburnum. The Guelder-rose, Water Elder (Viburnum opulus) and the Viburnum tinus. Here it is on a Viburnum tinus in my garden.
They hibernate as an egg deposited in the branches. They hatch in May. The greenish-yellow larvae cause much damage, but also the beetles feed on the leaves. Initial infestations will not kill the plants.
In June, the larvae will pupate in the soil.
Length 5 - 7 mm. Photos 27-8-2012.
