Beetles in the garden   

I have made subpages of some families. On this page I have placed a photo of one species of the family and a link.

In the water:

Dytiscidae.

Diving beetles, Predaceous water beetles, Dytiscidae.
This family is related to the ground beetles. Besides they can swim, they can fly too. The body has a streamlined shape. They store air under the elytra (the space between the abdomen and the elytra) They have no gills.
The larvae are also carnivores and aquatic. The beetles usually overwinter.
Sometimes I see a water beetle in the pond. But this was the first I found in the landing net, when I removed the leaves out of the pond.  Photos beetle 13/3/2010 Length: 10 mm.
It is mot easy to determine the dark water beetles from a photo. It may be one the family Agabus or of the family  Ilybius. The beetle looks like a Agabus bipustulatus.
      
Hydroporus palustris. Family predaceous diving beetles (Dytiscidae)... Hydroporus palustris. Family predaceous diving beetles (Dytiscidae).  Hydroporus palustris. Family predaceous diving beetles (Dytiscidae).
There are a lot of these small beetles in our pond. Most likely Hydroporus palustris, because that's a common beetle in the Netherlands. The resembling  Hydroporus species are rare.
The upper side is dark brown with brown yellow spots (variable), the underside is black.
They feed on small invertebrates. The adult beetle overwinters under water.
Length about 3,5 mm. Palearctic.

I do not know the species. Dytiscus marginalis is common, but there are more Dytiscus species in the Netherlands. Namely: Dytiscus circumflexus, Dytiscus dimidiatus. Rare: Dytiscus circumcinctus, Dytiscus lapponicus. Very rare: Dytiscus latissimus, Dytiscus semisulcatus. In Europe, Asia, North Africa and North and Central America are 26 species in this genus
The differences you can see on the underside. It has a yellow border. The elytra of the females usually have grooves, the elytra of the males are smooth.
The larvae and beetle are predators.
The length of this beetle I guess about 3 cm. A large beetle. Photos: 11-9-2012.

It looks dark brown, but as can be seen on this photo, the elytra are golden yellow with a dense black punctuation. A pale yellow coloured edge and a diamond-shaped spot on the neck shield. The underside is black.

Helophorus ís the only genus in the beetle family Helophoridae (traditionally included within Hydrophilidae as the subfamily Helophorinae).This beetle (6 mm) I saw in the pond on a leaf. I recognized it as Helophorus. But I had to askspecies. 
Ton van Haaren.: Helophorus grandis or Helophorus aequalis. They are very similar. Thanks Ton.
  It lives in water, it is therefore not as well adapted in terms of body shape such as the Dytiscidae. The body is elongated, but is interrupted between pronotum and elytra. The pronotum has irregular, longitudinal grooves. 
You'll find them
near the water plants. They can fly. After the photo left, this beetle flew away.  Photos: 9-11-2011.
       

Hydraenidae. 
 A family of small aquatic beetles with clubbed antennae. They do not swim well and are generally found in marginal vegetation.

I found it on the compost heap. Less than 3 mm. In Europe there are known 23 species. They are all very small.
They live in manure, compost and  in marginal vegetation.

Not in the water:

Darkling beetles (Tenebrionidae).
I
n some websites, books you see, that the Tenebrionidae family is subdivided into subfamilies as Lagriinae (for example Lagria) and Alleculinae (for example Cteniopus sulphureus). Others create separate families: Lagriidae and Alleculidae. It's very confusing.

They have a soft body and are rather sluggish. But they can fly. The brown wing cases are very hairy. The head and torax is black.
They eat among other things nectar and pollen.
The larva feed on
decaying matter in leaf-litter and turf.
Length: 7-10mm. Flying time: May – August. Lagria atripes is earlier than Lagria hirta. Photos 2-7-2011 German: Wollkäfer.

The beetle can be found under the loose bark of oak, but also of other trees. This beetle I had, for instance was found in a pine tree. The larvae are found in the ground with rotting wood.

Soldier beetles (Cantharidae) 
In the Netherlands are 50 species of the soldier beetle. Another
name is leatherwing. They are soft-bodied, straight sided beetles. Named soldier because the colour of these beetles is similar to a 19th century army uniform.
T
hey hunt  for small insects, eat nectar and pollen on the top of flowers.

19 May a number of this species flew in the garden. It was difficult to take photos because they were continuously in movement. This I had written some years ago. I still see them every year in May in our garden.
It is a
smaller relative of the Cockchafer or May Bug. It appears on sandy soils. Garden chafers have chestnut brown wing casings which are covered in tiny hairs. They have fan-like antennae, like all chafers. The wing cases are chestnut brown and are covered in tiny hairs.  
After the females have deposited 70% of the eggs, they start a short feeding period on trees and shrubs and cause damage to fruit trees. The rest of the eggs are laid on another place.

Eggs have a developing time of four weeks. The larvae feed on the roods of the grass and can cause much damage. They pupate in October and hibernate as a pupa in the soil.
Size: Approximately 10mm long.   Flying time: May-July.

The larvae (grubs) live two years before they pupate. They feed on plant roots (grasses, lilacs). In some articles is written, they are harmful to lilacs. But in my garden I notice nothing.

Very variable in colour. Head and pronotum are usually metallic green. The elytra can be brown, but also metallic green. If they have brown elytra, they resemble the garden chafer, but they are less hairy and larger. 
They are common on sandy soil. The larva or grub feeds on the roots of grasses. The beetle eats mainly from the leaves of the willow.  June-July. Length 12-15 mm.  Photos 25-6-2014.
       


Click beetles (Elateridae)

In the Netherlands there are about 70 species. They can flip themselves 30 cm in the air, when they are in danger. Sometimes they land on their back. But that’s not a problem. They will flip again. A pointed projection suddenly snaps, when the beetle arches its body. This causes a clicking noise. Which species they are, is difficult to say. 
The beetle eats vegetable food like nectar, pollen, thumbs and flowers
The larvae are called wireworms. They feed on the roots of plants, and they often cause much damage. This site gives you an idea of the different species:

Probably a larva of a Agrypnus murina. Determining the wireworms isn't easy. The shape of the rear end is slightly different in shape for the larvae of the species.
Wireworms live on plant roots and therefore they can be harmful. However, the larvae of the Agrypnus murina also live on other insects and larvae.
       


Jewel beetles or metallic wood-boring beetles (Buprestidae).  
Most of the family jewel beetles have a beautiful metallic colour. There are more than 15,000 species in the world. The shape is very recognizable. (oblong, narrower rear end) Most jewel beetles live in the tropics.
The larvae look a bit like a tadpole and they live under the bark. They can cause much damage.

Then this jewel beetle must be Agrilus cyanescens. The larva of this species lives in honeysuckle. (thanks for the Information Toon)

A copper-coloured beetle. The larvae make holes under the bark of pear trees. The holes are recognized by the zigzag pattern. They hinder sap flow under the bark. and branches or the tree may die. Other host plants are hawthorn and rowan. So they can be very harmful. Too bad because it's such a beautiful beetle. The beetles aren't seen much. Probably because they live short.

Looks like a gnat or wasp. With narrow pointed elytra that do not completely cover the wings and orange abdomen. It has feathered antennae. The female lays her eggs on rotting wood. When a wasp uses that wood for its nest, the beetle larva lifts to the nest, where it parasitizes. Length about 10 mm.
