Hi Chris,
as for me "a nice 'new' species" sounds a little strange, very abundant here!


That's strange... I have one female from a window trap, one male reared from an unknown host on Pinus and one female that I caught last summer flying around a small pine tree on sand dunes. The big Pamphilid-wasps, which this guy is parasitizing are also not that common here! To my impression, this species is restricted to open, warm habitats with small pine trees here, so definitely not common! There are possibly only ten other findings from Finland.

As other parasitoids, tachinids too have substantial variation in their numbers from year-to-year and place to place and many of them are hard to detect without some effort in malaise-trapping. Sometimes even this is not effective: Last summer I got only one Phytomyptera minutissima from a malaise trap on my yard, but collected 8 exx indoors on windows...

To get any idea on the fauna just by active netting, one needs to have a lot of time on the field.
