I saw this nymph walking in the caravan. Unfortunately I haven't seen an adult bug. In the Netherlands it is found in the south. Because of the white rings on the antennas they are well recognized.
Several deciduous trees.

Palearctic, Europe, northeastern United States.

A nymph. The adult bug is completely metallic dark like the dark part of the the nymph.
It is a predatory species, but they also suck juices. Length 5 to 7 mm.

The adult bug overwinters. From July the new adults appear.
From Africa to northern Europe. It is also found in the Netherlands.

There are a some species, which are very much alike and all occur in the Ardèche. Namely Carpocoris purpureipennis, Carpocoris mediterraneus nose, Carpocoris fuscispinus and Carpocoris pudicus. The names are of the bugs on the photos are not certain!!!

The bugs are beautiful.

Length 7 - 8 mm.
Especially in the Mediterranean regio.

Like family members, the color varies from yellow to red. There are similar species E. oleracea and E. dominulus.
It hibernates as an adult bug and is often found on crucifers such as cabbage and cress.
Especially in Southern Europe, but there are also bugs found in the Netherlands and England.
Length 7 to 9 mm.

Lygaeus pandurus (nowadays also called Spilostethus). Family: Seed Bugs or Ground Bugs (Lygaeidae).

Characteristics: A white spot on the light brown wing membrane.
Length 10 - 14 mm.

A nymph of the Lygaeus pandurus

Pyrrho-coris =  red insect. a-pterus = without wings. But they have brachypterous wings. Brachyptery means, that the wings are very reduced and non-functional. The can't fly. Occasionally there are long winged firebugs (macropteer). 
They are strikingly red with a black head. Also striking are the black triangle and the two large black round spots.

This bug also lives in the Netherlands. You often see them in dense groups near lime trees. They feed on the fallen leaves and seeds. They live also on other plants, but don't cause much damage. They also eat dead insects and sometimes even living insects.
The firebug is a plant eater, but it causes little damage. Sometimes there hundreds of firebugs on the same spot. Especially after a mild winter.
Augustus - May. They overwinter in colonies.
Palaearctic. Length 10 - 12 mm.

Length 6 - 8 mm.
The adult bug overwinters.

Key of bugs of the family Rhopalidae in German.

They are variable in colour. From yellowish to reddish brown.
Also in the Netherlands.

Length about 5 mm.

A treehopper Stictocephala bisonia, Stictocephalus bisonia. Family Membracidae.

Native to North America. Spread in Europa early 20th century most likely via the fruit. It is now in Southern and Central Europe, Central Asia and North Africa. 
Bisonia refers to the resemblance of its profile to that of a bison. It has a the triangular shape and the sides of the front develop into small points. It has transparent wings.
This bright-green treehopper feeds upon sap from leaves of trees and plants as willow, elm, goldenrod, clover. But also fruit trees and vines.
The eggs overwinter in the branches. The female bores with its ovipositor a hole for the eggs. The nymphs appear in May, June. They crawl down and feed on grasses and weeds.

Length: 6 - 8 mm

Maybe Cicada orni. Family Cicadidae.

Maybe  Family Cicadidae.

About 25 mm. One of the known singing cicada. In the Mediterranean, you always hear them. You see them much less. If they sit against a tree, they are very well camouflaged. Closer up, they stop making noise. This cicada was sitting on a beautiful spot.
The larva of a singing cicada lives underground for several years feeding on juices of plant roots. The adult cicadas don't live long. (Several weeks to several months)

This dragonfly is no longer in the Netherlands. Usually around not too fast-flowing streams and rivers with shrubs and trees along the shore.

Often near running water. The eggs are laid in water plants.

Not as large as the Megascolia maculata flavifrons. You can see it is family. 
Length about 20 mm

This beautiful spiderwasp hunts large orb weaver spiders (Araneidae), for example, the wasp spider (Argiope bruennichii)  Argiope lobata, Araneus
angulatus and Araneus ventricosus. The spider is paralyzed with a poisonous sting and then dragged into a hole. In the abdomen an egg is laid. 
They have orange wings with dark tips.

Another Tachinid. Two members of the subfamily are on the page "Tachinidae".
From Southern Europe to Slovakia. Not in the Netherlands.
June - September.

Most of these flies are kleptoparasites of solitary bees and wasps. They lay an egg in the nest of these bees and wasps. The larvae eat the food intended for the bee and wasp larvae .
They are not to identify from a photograph .

May - September.  North Africa, Europe
Length 6 - 9 mm.

These hoverflies are tiny flies from 4 to 7 mm. Sometimes they are completely black. Sometimes the abdomen is for a part red (or yellow). The paragus in this picture has the length of about 4 mm. The species I don't know.
The larvae feed on aphids.

                  Cyllenia rustica Also of the Bee-fly family (Bombyliidae)

The eggs are laid on species of Mallow like common mallow. I have these plants in the garden. But I live far from Limburg. And that's the only part of the Netherlands with Mallow Skippers.
Light brown wings with dark brown spots. Forewing length about 14 mm.
Flight: April - October.
Southern and Central Europe. Rare in the Netherlands (Limburg).

Speckled Wood (Pararge aegeria) subspecies Pararge aegeria aegeria. Subfamily Satyrinae. Family Nymphalidae.

Europe. In the Netherlands only a migrant butterfly.
Host: Different species of violets. The young caterpillars hibernate. Eggs are deposited on trees near violets.
May - September.

    Willem Baltussen...thanks for the correction!

I have described this moth on my page "butterfly". Because I see it a sometimes in our garden.
In France I saw it more often. But I still have not a good photograph. They so very active..

This is also a beautiful shiny beetle. But it is black instead of green. On the shields are white spots.
Central and South Europe, North Africa, Asia Minor, Middle East. The Oxythyrea funesta is found in the southern Netherlands, but it is rare.
Length 8 - 12 mm.
In the Netherlands: May-July.                                                                                                                                                                          

The musk beetle is also in the Netherlands, but is quite rare. Especially in my neighborhood.
It is a large beetle with a length of 3 to 4 cm. (compare it with the Striped Shield bug (Graphosoma lineatum) It is black with a blue green black metallic sheen.
It lives on willow. A larva can be there two to three years in life. Occasionally you will find the larvae of the poplar and alder.
If he feels disturbed, it spreads a musky odor. Hence its name.

Typical are the three broad white bands on the elytron.
Central Europe, Southern Europe, Turkey.
The larvae develop in two years in stems and roots of various plants, especially herb stall (Ononis), but also in other family members.
May-July. I saw a lot of these longhorn beetles.
Length 6 to 12 mm.

A yellow green beetle with black bands. On the neck shield is also a black transverse stripe. The upper band on the elytron is shaped like a horseshoe. I have seen a lot of these longhorn beetles, hut I do not have many pictures. When I put photos on the computer, I noticed that a part of the antennas was missing. The beetle had no problems with it.
He lives in Europe but not in the Netherlands.
The larva is found in woody plants in the stems of herbaceous plants. There it stays two to three years.
May - September.

The larvae develop in the wood. There are several species in the area near the Mediterranean See, Middle and Eastern Europe.
They have shape of the jewel beetles in our garden, but they don't have shiny elytra. On the elytra of these species are short thick hairs..
June-August.

Trichodes alvearius is very similar, but this species has red around the last black spot. 
The beetles feed on pollen but also on small insects. The larvae live in the nests of honey bees and solitary bees and feed on the pollen and the larvae of the bees.
Central Southern Europe. Rare in the Netherlands.  
Length 9 - 13 mm. May to August.

They feed on aphids and larvae of leaf beetles. This ladybird also lives in the Netherlands. But unfortunately not in our garden. The spots at the rear and of the elytra can be small. Then they are more difficult to recognize.
Length 3.5 - 5 mm.

A black rounded beetle with red elytra. Like ladybirds, they release a bitter, smelly liquid, when they feel threatened.
It lives on poplar and willow. In Europe and the Netherlands is a general bug. I miss both trees around the garden. Therefore, I had no photo of this leaf beetle.
The adult beetle overwinters.
Length to 13 mm.

In any case, a leaf beetle. That's all I know.
Maybe Cryptocephalus sulphureus, Cryptocephalus fulvus, Cryptocephalus luridicollis

European mantis can be recognized by the dark spot near its armpit, the line over the eye. The neck shield about half as long as wings / abdomen. Usually they are greener than the European mantis in the picture.
Native to Southern Europe. But now also in the U.S. and Canada.
They are more akin to cockroaches than to grasshoppers. I haven't photographed grasshoppers. Another time perhaps.
This praying mantis was in the sun on a place with much shadow.

Perhaps Ectobius pallidus, but Ectobius vittiventris is also possible. If you know the name, you can mail me. I do not know much about cockroaches.
Usually, you read, that they are household pest insects and that they are difficult to control. But it is a beautiful insect.
