Spiders belong to the class Arachnida. Arthropods such as
scorpions, harvestmen, ticks and mites are also among that group.
The rear body (abdomen) is softer than the front. The head and
the thorax with legs are fused. This part of the spiders is called prosoma. The head and the thorax with legs are fused. This part
of the spiders is called prosoma. They have eight legs. The first pair of legs is usually the longest.
No real antennae only
two palps, which are used to sense. The adult males and females have
different palps. The palps consist of six segments. The last segment of the adult male is
knob-shaped. This bulbous segment stores the sperm packet just before
mating. The mating can be dangerous to smaller males. The males of some
families are sometimes eaten by the females after mating.
Most of the spiders have eight eyes. But there are also spiders with six
eyes. The eyes are not as great.
They are predators. Their method of hunting is different.
Wheel-shaped webs are best known.
Not all spiders us webs to hunt. The bite of spiders in the Netherlands is
not dangerous for humans.

Family orb-weaver spiders (Araneidae)
These spiders make spiral wheel-shaped webs. Peopleoften askhow
thefirstthreadis attached.
From a point they release a length of a thread in the wind. They
waituntilthe
threadis stuckto another point. Then theweb
can be made.
European garden spider, diadem
spider, or cross spider (Araneus diadematus). Family orb-weaver
spiders (Araneidae).
At the end of the
summer the garden is full of webs. Many webs are from the European garden
spider. They often span a great distance.
The females are adult in the second year of
their lives. They are much larger than the males. That is at the end of
the summer. Hence the many big webs. The mating is risky for the males,
for they can be eaten by the female.
When it is freezing the adult spiders die.
The eggs are in cocoons and are deposited in
autumn. This way they hibernate. The young spiders, which hatch in the
spring, release long silken threads to travel on the wind to other
areas. (ballooning)
Cross spider because of the the white dots on its
back forming a cross. Its colour is from light yellow to dark grey.

Walnut Orb-Weaver Spider
(Nuctenea umbratica) Family orb-weaver
spiders (Araneidae)
Walnut Orb-Weaver Spiders have a flattened body, with a leathery skin.
The spider on the photo was
on top of the window. It felt threatened by me. When it failed
to hide, it let itself down to the ground on a safety line. Then it
pretended to be dead. It folded its legs around.
The spiders are nocturnal and shy by day. It is hiding under the loose bark of trees. You also
often find the spider around houses. The web looks like the web of a cross spider. From the web the spider
makes a signaling thread to the hiding place. After dusk it sits in the
center of the web. Especially moths should
beware.

it is is the M. mengei. This feature applies only to males.

The spider has got its name vibration spider, because it is shaking when
it is threatened.
Just like in our house you can find this spider in most houses and barns. Often in dark places.
They make a rather messy web. Often near the ceiling. When the web is
dirty, they make a new one. They don't eat their own web like many other
spiders. My wife is not very happy with these webs.
The spider throws tough web material over the victim in the web until it is
harmless.
The eggs are held together with a few wires. The female hold the eggs in

The silk, they spit is poisonous. In the head-thorax are silk glands, which are connected to venom glands. They also have silk glands in the body behind.
The females carry the egg mass under their body.
In the Netherlands they mainly are found in the houses, for the winters are too cold for them.
Originally they live in southern Europe.

Nursery web spiders make egg sacs, which they first carry under the body. When
the eggs are about to hatch, the cocoon will be attached to a plant. Therefore
the female spider will build a kind of woven tent. A nursery tent. That's why they got the name nursery web spider. In the Netherlands there are two
genera. Pisaura and Dolomedes.

On this photo the spider is sitting on the bamboo, which is designed for masonry bees to make nests in it. I am not really happy.
Under the leaves you can find cocoons with eggs, which are guarded by the
females. The males are able to produce audible sounds by vibrating the abdomen
against the leaves (for the females).
From light brown to grayish brown. They can be identified by the triangular dark spots on the rear body.

quickly paralyzing venom. It's a small spider from 2 to 4 mm.
This is the Ero aphana or the Ero tuberculata. I saw the ero after I had photographed
an Enoplognatha nest. Mother Enoplognatha guarded the nest but did not see the
ero. She wasn't attacked by the ero.
The eggs of an ero are laid in a cocoon surrounded with a wiry silk and is
hanging by a silken thread. More
information.

I want to thank everyone, who has helped me (waarneming.nl)
to identify. In particular, Jacomijn Prinsen, Willem
Boomkens, Frits Broekhuis, Joost Vogels and Pierre Oger.
Harvestmen, order Opiliones formely Phalangida,
class Arachnida.
Daddy-long-legs, but this name is also used in conjunction with crane
flies and cellar spiders in the family Pholcidae.
In 2010 I will
take more photos of harvestmen. They look like spiders.
Features: The two main body sections are grown together to an oval
shaped body (difference with the spiders) They also have no venom or
silk glands. Usually they have a single pair of eyes. The second pair legs
is the longest and works as antennae or sense organs.
Most species are maturing in late summer - hence their common name.
Most harvestmen are active during the night.
Harvestmen catch small insects and other small species, but they also eat
the decays of any dead animal and all kind of plant material and fungi.
A leg (or legs) easily becomes detached from the body. This is
a means of protection from predators. When detached, a leg will
continue to twitch for some time. (sometimes even up to an hour)
They lay eggs in moist soil, under rocks or logs.

Red Harvestman, Opilio canestrinii
female in the holly. Photos 13-12-2009.
Striking is the difference in
colour of the male between the orange body and the dark legs. (but
yellow "knees")
The legs of
Opilio parietinus and Opilio saxatilis are less dark. They look like the Opilio
canestrinii.
The Opilio canestrinii has invated Europ fom the Apennines. Since
1993 it is found in the Netherlands. In England in 1999. It lives on
the walls. Other species at walls Opilio parietinus and Opilio saxatilis
are wiped out by the Opilio canestrinii. Most likely the eggs and
harvestmen are imported by transporting plants.
Body
length males: 4 - 6 mm. Females: 5 - 8 mm. The female is yellowish brown
to ocher. The legs has light and dark rings. The eggs are laid in autumn.
Adults June - December. Thanks Arp Kruithof for your
help.
Spring Harvestman (Rilaena
triangularis).
The spring harvestman is grown mid-April. And is therefore the first
harvestman you see in the spring. April to June. This harvestman don't overwinter as an egg, but as a nymph.
(like the in the Netherlands rare Platybunus pinetorum)

Dicranopalpus ramosus.
A harvestman with very long legs (up to 5 cm).
In resting position the legs are stretched to the sides. It is also
distinguished by the forked pedipalps.
Native to Morocco. (Discovered in 1909) In the Netherlands it is
discovered in 1992. Now it is a general harvestman. August to November.

Phalangium opilio.
A harvestman which can be recognized by the elongated spot on the back with two narrows. (Looks like Mitopus
morio). The underside is light. Length 6 to 9 mm. May to November.
Native to Europe, Asia. But now they live also in North America and North Africa.

Nemastoma lugubre.
In the Nederlands: N. dentigerum, N. lugubre en N.
bimaculatum. N. bimaculatum is very similar to N.
lugubre but is more rare.
It is a dull black harvestman with two striking silvery white spots.
Length body: Male: 1,6 - 2,7 mm, female: 2,1 - 2,7 mm.
The whole year.
