Hymenoptera. The bees, bumblebees, ants, wasps and saw flies belong to that
order.
Hymenoptera is divided into different subordes. Namely suborder Symphyta
(This group has no waist, sawflies) and
suborder Apocrita. Apocrita is also divided into two groups. Namely: Parasitica and
Aculeta.
Parasitica: wasps or parasitic hymenoptera. The females have an ovipositor, with
the ovipositor they lay eggs into or near larvae. These larvae are eaten by the wasp larvae. There are several families.
The largest group are the ichneumon wasp (Ichmonidae). Other groups are: Braconidae,
chalcid wasps (Chalcidoidea), Gasteruptiidae, gall wasps (Cynipoidea) The plant
galls develop, when the eggs are laid.
Aculeata: In this group the ovipositor is is modified into an
stinger. With this stinger they can defend themselves (bees) or they can
stun a prey. In this group are also wasps with parasitic larvae. Spider
wasps look like ichneumon wasps, but have a sting to stun their hosts.
Jewel wasps (Chrysididae) have a sting too.
Ichneumon wasps, Ichneumonidae
There are many species in the world. (60.000 species worldwide) Ichneumon
wasps are parasitoids of other insects. Their abdomen is very
elongated and have long antennae (at least 16 segments)
They are solitary. There are many subfamilies. On this
site you can find the indentification keys to the subfamilies of
Ichneumonidae. but it isn't easy.
Anomaloninae
A small Ichneumon wasp. Subfamily Anomaloninae.
Family Ichneumon wasps, Ichneumonidae
They are Endoparasitoids (koinobiont) of moths,
butterflies and beetles. (larvae)
They have a slender abdomen. 38 genera. On this photo: on a leaf of a Goldenrod.

I think
it looks like the Stenarella, but the ovipositor is much shorter. On the trunk of a dead apple tree. This is not without danger, because there also lives a
Marpissa muscosa (a large jumping spider).

A beautiful large Ichneumon wasp. When I photographed this wasp, I thought
that is should be possible to determine. Unfortunately it was not
possible...... so large, so beautiful and yet no name.
The
answer of Pierre-Nicolas from Belgium was: A male of Pimplinae like
Dolichomitus, Liotryphon, Ephialtes,...

Correspondence with Gergely Várkonyi:
Gergely: This wasp belongs to the Polysphincta
group of genera in Ephialtini (Pimplinae). Possible genera are (e.g.)
Polysphincta and Oxyrrhexis.
Ik: I have searched on internet. Oxyrrhexis carbonator is a similar species,
that is if the pictures on internet are right .
Is this species one of the possibilities?
Sure, O. carbonator is one of the
possibilities. But Polysphincta spp.
look similar. (spp: species pluralis, multiple species)
Thanks Gergely.
About 1 cm. On a horse chestnut. They are so beautiful, but so difficult.

No Netelia testaceus, for the and of the body of
this species is black. The other species are difficult to identify.
Furthermore, they can also be confused with
ophion species. But the veins of the wings are different.

Perhaps a species of the subfamily Tryphoninae.

I don't know the species. But it looks like Cosmoconus elongator. Another species in the Netherlands
Cosmoconus ceratophorus.
In August I see them flying in the garden. It has a distinctive orange abdomen. The legs are black and yellow. The antennae are dark orange.
Size is approximately 10 mm.

Although this little insect looks like an ant it is a wasp.
On forum "hymis":
Henrik Gyurkovics thinks: It could be fam.
Ichneumnidae, subfam.Cryptinae, and there is a remote possibility that it is
some Gelis spec.
Thanks Henrik
Wasp in the genus Gelis are wingless.
An example of a difficult Ichneumon wasp.

About 1 cm. Very late in the year. Even the subfamily is not possible.

Wereldwijd is dit ook een heel grote groep met meer dan 10.000 soorten.
Antennes hebben 17 of meer segmenten. Een slank lichaam.
Spathius spec. Family Braconidae
A small Ichneumon wasp from about 4 mm on a rotten plank. It was well camouflaged.
The Dutch expert Kees van Achterberg has written (translated): The
Braconidae wasp is indeed a Spathius (gregarious ectoparasitoiden of beetle
larvae live in wood), but the species can not be determined without the
specimen in your hands. It is a problem group to identify, even if you have
a specimen!
I want to thank Kees van Achterberg and Pietsje, who
has asked about this small wasp to Kees.

Gasteruptiidae.
Characteristic of this family is that the metasoma
(the posterior part of the body) is very high attached.
The eggs are laid in nests of solitary bees. Antenna segments 13
(males) or 14 (females) The hind tibiae are swollen and there are 3 red bands on the abdomen.
Family Gasteruptiidae.
Probably Gasteruption assectator. Family Gasteruptiidae.
The female has a short ovipositor. Similar to the larger Gasteruption
jaculator. But the female has a long ovipositor. However, there are more species in the Netherlands.
Length 8 - 12 mm.
Two other species.

Gall wasps, Cynipidae.
Most females in this group lay their eggs with their ovipositor in plants.
Than the plant galls develop. Ibalia leucospoides, described below, does not lay
their eggs on plants.
Ibalia leucospoides
Family Ibaliidae, Gall wasps (Cynipidae)
In the Netherlands very rare!!!!!
It is a parasite of wood wasps of the genera Sirex, Urocerus and
Xeris which live in 'pine'.
A very special wasp. The abdomen is very narrow. It has the wings along its
abdomen. The veins look very different to the veins of other wasps. Antenna female: 13 segments. Male 15
segments.
In the Netherlands there are known are two species: Ibalia leucospoides (Hochenwarth, 1785) and Ibalia rufipes Cresson, 1879. Worldwide there are not too many species.
Length to 15 mm.
Holarctic region; introduced to Australia, New Zealand and South Africa
