Wasps, bees, bumblebees
Hymenoptera. The bees, bumblebees, ants, wasps and saw flies belong to that
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
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:
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.
I have made subpages of some families. On this page I have placed a photo of
one species of the family and a link.
Large Rose Sawfly (Arge pagana) Family Argidae, Saw Flies
(Symphyta). Sawflies are closely related to wasps. But they don't have
the 'waist' of wasps. They
make no nest and have no social organization. Sawfly larvae feed on
leaves. The larvae look similar to the caterpillars, but they have six or
more pair of prolegs. Some larvae look like little slugs.
Ichneumon bucculentus Ichneumon wasps
Ichneumonidae belongs to the group Parasitica. The females have an
ovipositor. Larvae are parasitic.
Large Earth Bumblebee, Buff-tailed Bumblebee
(Bombus terrestris) Bumblebees
Bumblebees (Bombus): Big hairy bees of the genus Bombus. They live in colonies. Only the queen
hibernates and starts a new colony next year. The nest is sometimes underground, but can also be built between
clumps of grass.
Social Wasps (Vespidae) Subfamily Paper Wasps, True Wasps
(Vespinae) The other subfamily: the Potter Wasps
The colonies exist one year. Each year the queen starts building a small nest. The nests are
constructed of paper. The paper is made of wood. The wasps have made the paper
by chewing on wood. The first wasps are the workers. In one year there can be
thousands in a colony. At the end of the summer the males and new queens appear. Only the fertilized queens
True wasps have their wings folded longitudinally when at rest. The eyes are kidney shaped.
European hornet (Vespa
Family Social Wasps (Vespidae).
A queen. A very large wasp. Reddish brown on head and thorax. Resembles the Dolichovespula media, but Vespa crabro has completely reddish brown antennae.
Queen length: 25-35 mm, workers 18-24 mm and males 21-28 mm.
Nests in hollows, especially tree hollows.

Family Social Wasps (Vespidae).
Thie first photos are from a queen. As you can see the queen more robust. The antennae of the males have 13 segments. The scapus (shaft) is the first segment. The workers have 12.
In Holland they are also called lemonade wasps, because they can be annoying in late summer and autumn.
Especially if you drink lemonade.
Queen Length: 16-19 mm, length workers 11-14 mm, length males 13-17
They look very much like the slightly larger German wasp (Vespula germanica).
The nest will be built underground in old nests of animals, but also in hollow trees and wall cavities.
In 2008 we had a nest between the roof and ceiling of the pantry. Until autumn we had no problem. Only when it was cold, you did see them in the pantry.
There they were walking around very slow. The year after they had disappeared.

They don't bother people unless they come too close to the nest. The queen has a red drawing on the
thorax. The median wasp is variable in colour. Workers and males are often black with narrow yellow bands.

gazella, Ancistrocerus quadratus, Ancistrocerus nigricornis, Ancistrocerus
The nests can be found in holes in the wood. Like beetle galleries, boreholes. In the cells of the nest
are caterpillars as food for larvae. As with masonry bees, they close the cell. Photos 2-6-2011, 12-4-2012.
This superfamily consists of the Bethylidae, the Chrysididae, the Dryinidae and several smaller families.
The Bethylidae belong to the superfamily Chrysidoidea and have a sting. They are dark, small to medium sized wasps with a flattened body and short stout legs. The Bethylidae are parasites of larvae of butterflies and beetles. They paralyze their victims by stabbing them (difference Chrysididae). Then they hide it and lay their eggs. The larvae live as external parasites on their 'host'. There are five subfamilies: Bethylinae, Epyrinae, Pristocerinae, Galodoxinae and Mesitiinae (not the Netherlands).
Bethylus. Subfamily Bethylinae. Family
The four species in the Netherlands are Bethylus boops
(female 2,0-3,0 mm), Bethylus cephalotes (male 2,5-4,5 mm, female 2,5-5,5 mm), Bethylus dendrophilus
(male 2,0-2,5 mm, female2,5-3,5
mm), Bethylus fuscicornis (male 2,0-4,0 mm, female 2,5-4,5 mm). Differences there are among others in
the hairs. Not visible in these pictures.
According to Jeroen de Rond its probably a Bethylus dendrophilus
or a Bethylus boops. Both species have a a sharp triangular snout. B. dendrophilus
has bald eyes, B. boops has hairs on the eyes (not visible in these
pictures). They are both arboreal species.
The Dryinidae belong to the superfamily Chrysidoidea and have a sting. Behoren tot de superfamilie Chrysidoidea.
The larvae of dryinidwasps are ectoparasite on cicadas.
Adult female dryinidwasps usually have a chelate foretarsus for grasping the
cicada during oviposition. The cicada stays alive at that moment. The larva of the wasp
only has the head through the skin of the cicada and is feeding internally on the host.
When it grows it develops a hardened sac-like "case" to protect its vulnerable body.
The host is eventually killed. Pupation occurs on a plant or in the soil. It
overwinters as pupa. They look like an ant and they live often near ant nests.
| Anteon brachycerum. Family
The larvae of Anteon brachycerum are ectoparasite on cicadas.
Determined by Jeroen de Rond. Information Jeroen (translated): This miniature wasps are almost impossible to determine from pictures, but this is an exception. The big yellow wing stigma and the thick, beads-like antennae are typical. The species lives as larvae parasitic on birch cicadas. The cicadas have a kind of brown pouch on their backs. From the Netherlands are only about 20 known discoveries since 1980.

Ruby-tailed wasps, jewel wasps, cuckoo wasps
Ruby-tailed wasps have a beautiful bright metallic colour. In the Netherlands and Belgium are about 60 species. Identification
of many species is not easy.
They do possess a stinging organ although there is no venom. (most species).
They have a hard
exoskeleton. They need it to protect
themselves, when they meet the host. For Ruby-tailed wasps lay their eggs in
the nests of other wasps, bees. (cuckoo wasps) The larvae of the ruby-tailed
wasps eat the bee or wasp larvae of their host. They are variable in size.

Of Chrysis ignita a distinction is made between some subspecies. Depending on size and host.

Spider wasps, Pompilidae.
Spider wasps, Pompilidae
species it is, I don't know. Spider wasps are slender with long legs. Usually they are black with a red or white markings on the front part of the abdomen. Unlike other wasps the first segment of the thorax
(pronotum) of spider wasps extends back to the tegulae (attachment scales of the wings).
They are solitary and hunt spiders. The spider is paralyzed with a poisonous sting
and then dragged into a nest. Or to a place where a nest is made. In the abdomen an egg is laid.
In Belgium and the Netherlands are approximately 70 species. There are four subfamilies.
Ceropalinae, Pepsinae, Ctenocerinae, Pompilinae
They can also stabbing people.

The digger wasps are divided into 2 different families, the Sphecidae and

kind of prey. The prey depends on the wasp species. Mostly insects, but
Bembix rostrata. Family Crabronidae.
The largest wasp in the family Crabronidae in the Netherlands. In sandy regions such as the dune area. Nests in the sand with only one larva that gets prey (mainly hoverflies and other flies). A yellow-black abdomen with wavy bands and green eyes. A beak-shaped

A black bee with white spots and a red-brown and reddish-brown scutellum shoulders.
The differences between the two species are small. The females Epeolus variegatus have black
hind thighs (but that may be on the underside!) And Epeolus cruciger has red hind thighs.
Like wasp bees Sphecodes are parasitic bees. (Most of groove bees) Many species are also very difficult to identify from a photograph. Usually they are black with a partially red abdomen. In the Netherlands there are 20 species. They don't carry pollen. Especially in the sandy areas they are common. (dunes)

only the side is the red.
