Ground beetles   

The ground beetles, I will place on this page
There are about 400 species in the Netherlands. They differ in size. Most species in these families are carnivores. 

Subfamily Badistrinae.

A two-coloured beetle (orange and black). Length 5-6 mm.
In the sun it gets a beautiful glow. 
In this family are more beetles with this colour. The end of the first segment of the antenna of the Badister lacertosus is donker. The whole first segment of the antenna of the similar Badister bullatus is orange. Badister unipustulatus is also very similar.
I found this beetle in March under a pot in leaf litter. 
     

 

Subfamily Carabinae.

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

One of the largest beetles in Europe. Especially the elytra and neck shield his shiny blue to blue-black. The elytra is longitudinally ribbed. It looks like the Carabus violaceus, but this beetle has smoother elytra and is a bit more elongated.
It is active at night and is hidden during the day. It is mostly found in forests and heathlands.
May - September. The beetle or larva overwinters. Europe. Length 20-30 mm.

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

The Cicindela hybrida resembles the in the Netherlands rarer Cicindela sylvatica. According to the Dutch Forum "waarneming" are the differences:
Cicindela hybrida: Upper lip (labrum) yellow, without sharp keel. Elytra brown with strong metallic shine, yellow spot at the rear end of the abdomen. General in sandy areas.
Cicindela sylvatica: Upper lip black, with sharp keel length in the middle. Elytra black brown with faint metallic shine and three yellow spots, the back spot is pointed on a distance of the rear end, in the middle of the elytra irregular shallow dots.
Both the larva and the beetle have very large jaws. They live on a sandy bottom, like here in the dunes. You see them alternately walking and flying. The larva lives in a hole in the sand.
Length 14-20 mm. April - October. Europe.

A slender reddish brown beetle. Legs and antennae are yellow-brown. It looks like the beetles from the genus Dromus. The adult beetle feeds on small insects, but also with pollen and seeds.
Generally, both in dry and humid biotopes. The adult beetles overwinter.

Legs and antennae are yellowish. The neck shield and the front part of the head are reddish brown, the remaining part of the head and the elytra black-brown, two yellowish spots on each elytra. Often found on the bark of living trees.

When you find such a small groundbeetle mostly it is a Syntomus or Microlestes.
Syntomus foveatus is a bronze black ground beetle. Often on dry sandy soil between litter.

This ground beetle is easy to recognize because it has long bristles on the first six segments of its antennae. 
Length 6-8 mm. It prefers damp places. This ground beetle feeds on mites and springtails
It hibernates as an adult beetle. Native to Europe and America.  Photos 20-03-2012.

A small, dark, shiny bronze ground beetle. Length: 3,5-5,5 mm. 
They have large, conspicuous, bulbous eyes They use their stereoscopic vision to locate their prey.
They are found under rocks, leaves and moss. But during the day they sometimes run across the tiles on our terrace. They are difficult to photograph because they always run like other ground beetles. There are many species. But they are difficult to determine.  
Both adults and larvae are predatory. They feed on small insects like springtails

In the Netherlands there are already about 40 species, many of which are difficult to identify. They are usually 'bullet-shaped'. They are carnivores, but they also often feed on plant food. Length about 7-8 mm.
They can be found under stones, leaf rosettes, between grass roots and under dense vegetation. I also regularly see them (like the beetle in the picture) walking on the terrace.

Larva ground beetle.   Larva ground beetle.
This beautiful beetle larva walked over my terrace. I don't know which beetle beetle it is. The larvae of ground beetles are carnivores and feed on prey such as insect larvae and springtails. The larvae are elongated and live in or on the soil. Photo 4-3-2011
