Family Tachinid flies, Tachinidae.
There are species with a length of 2 cm, but also with a length of 2 mm. The colours are very
different. Most tachinidae have many bristles.
The larvae develop inside a living host. Mostly
the host will be killed. The host can be a caterpillar, larvae of beetles,
sawflies
etc.
The family Tachinidae is divided in subfamilies.
Namely: Dexiinae, Exoristinae,
Phasiinnae, Tachininae. These subfamilies are divided
in Tribes. The Tribes are divided in genera.

Subfamily Dexiinae
"Ovo-larviparous": The eggs
either hatch inside the body or immediately after laying.

Campylochaeta praecox looks like other tachinid flies, but you only
can find this fly in spring. The shins are slightly reddish.
Hosts: Feathered Thorn (Colotois pennaria), Scalloped Oak (Crocallis
elinguaria) and Peach Blossom (Thyatira batis).

Comment Chris raper: Looks like a Phryxe cf. vulgaris to me (upturned,
crossed apical scutellars, hairy eyes, bluish-grey dusting on frons etc.)
but it seems quite early in the year for that species.
Perhaps because the beautiful weather in the Netherlands in March.
