Family Tachinidae
There are species with a length of 2 cm, but also of 2 mm. The colours are very
different. Most tachinidae has many bristles. Information: http://en.wikipedia.org/wiki/Tachinidae
The larvae develop inside a living host. Mostly
the host will be killed. The host can be a caterpillar, larvae of beetles,
sawflies
etc.
Tachina fera
Family: Tachinidae
Tachina magnicornis is also possible.
This fly was very striking that day between the
hoverflies.
It is very easy to recognize by the red back with the black stripe in the
middle and the stiff hairs.
The larva of the Tachina fera feed on caterpillars. The eggs are laid on
the leaves. The larvae move towards their host and get
into their body. After about two weeks, it changes into a fly.
Larvae of other Tachina species parasites on larvae of other insects.
Length: 9 - 16 mm
Tachina magnicornis: The black belt on the
back is wider and wider at the end. (not always)
Ernestia rudis Family: Tachinidae
Another Tachinid.
It's a
robust, dark fly.
Bessa selecta Family: Tachinidae
Comment Jaakko: Just a combination of features: sharp
kink in the m-vein, white hairs behind the head, low "short-legged"
sitting position and small size.
Blepharipa pratensis
family: Tachinidae
Photo May 2009.
It is a rather large fly. Slightly larger
than a bluebottle.
On internet you can read about investigations with the Blepharipa pratensis.
Because it is a parasite of the gypsy moth, Lymantria dispar. A
day active moth. This moth is a pest in North America.
This is the caterpillar of the gypsy moth. It walked on the same shrub.
Dexiosoma caninum
Family:
Tachinidae
A striking fly with a light brown back, and
beautiful eyes.
The antennae are not as long as the antennae of many species.
I
read the larvae parasite the larvae of the cockchafer.
But I have no cockchafer in the garden. I have many Garden
Chafers
(Phyllopertha horticola). They are family. Perhaps....... But I don't know.
Epicampocera succincta
Family: Tachinidae
A shiny blue fly.
This fly is a parasite especially of caterpillars
of Whites. (family Pieris)
And these caterpillars are in the garden.
The caterpillars of a large white eating Annual
Honesty or Silver
Dollar(Lunaria
annua).
Eriothrix rufomaculatus
Family: Tachinidae
I read somewhere, this fly is a parasite especially of caterpillars
of snot moths (Pyralidae). But I am not sure.
Length 10 - 15 mm
German: Rotgefleckten
Raupenfliege
Gastrolepta anthracina Family: Tachinidae
A small fly. In May I see a lot of them in the garden.
I haven't found much information about this fly.
Linnaemyia spec. Family: Tachinidae
Not entirely sure. It is a fairly large fly.
Linnaemya tesselans Family: Tachinidae
You do see similarities between this fly and the Linnaemyia spec.
above. But this fly hasn't the brown spots on the side of the body.
Lypha dubia
Family: Tachinidae
Meigenia mutabilis
Family: Tachinidae
Not quite sure. It was sunbathing on an euphorbia
Mintho rufiventrisFamily: Tachinidae
Comments: It has large orange patches on
sides of the abdomen.
The larvae are parasitoids of caterpillars of the moth Orthopygia
glaucinalis and probably of the moth Ostrinia nubilalis.
The family can be recognized on the two hairs on the photo next to the bottom of the eye.

Phasia hemiptera Family: Tachinidae
The female lays their eggs on shieldbugs. The main hosts are (Pentatoma
rufipes) and the Green shield bug (Palomena prasina).
This is a female. The male is more colourful and has beautiful curved
patterned wings.
The fly looks like a hoverfly. It misses the bristles
of many other Tachinidae
Length: 12 - 15 mm.
Northern and Southern Europe.
April - September. Two generations.
Phorocera obscura
Family: Tachinidae
In April 2009 there were many in the garden.
It looks a bit like a flesh fly (Sarcophaga
carnaria)
Phorocera obscura Family:
Tachinidae
This fly was much smaller (8 mm) I thought, it was an other species.
This species varies in size. From 4 to 12 mm. Their size as adults depends
largely on the health of their larval hosts
Thanks to Theo Zeegers and Chris Raper
Phryxe spec., probably nemea Family:
Tachinidae
Ramonda spathulata Family:
Tachinidae
The larvae are parasitoids of caterpillars of the owlet moth (Noctuidae)
According to Theo Zeegers they are not so common in the Netherlands, but
more often seen in the dune area.
April - October (The most in May - June)

Siphona spec.
Family: Tachinidae
A small fly. About 5
mm.
Spec. because I don't exactly know which species it is. You can't
determine this fly fom a photo.
You can recognize Siphona to its long snout. If you look closely, you
can see it on the photo.
Subclytia rotundiventrisFamily: Tachinidae
According Chris Raper: Maybe a slightly teneral Subclytia rotundiventris. The
fly has a gray thorax and orange abdomen. This fly has gray spots. These
spots are usually not so good to see. In the middle of the abdomen on each segment is a dark triangular
spot.
Length: about 4 mm
May - September.
The larvae are parasites of the bugs of the family
True Shieldbugs (Pentatomidae)
and Acanthosomatidae.

TachinidFamily: Tachinidae
Sometimes it is not possible to identify fly
from a photo.
This fly unfortunately has no name.
I want to thank everyone, who has helped me (waarneming.nl)
to identify. In particular, Joke van Erkelens, Robert Heemskerk, Mark van Veen,
Gerard Pennard and Han Endt.
With the determination of Tachinidae I have had
much help from Theo Zeegers and Chris Raper. (On diptera)
