Another spiderwasp and again a new garden species, a female Priocnemis fennica ^[1,2]. This is an uncommon wasp in the Netherlands ^[3].

She was foraging on and around the window frame probably looking for spiders I assume.

See also the approved pbservation on Waarneming.nl.

The species can be identified using the following characters ^[2]:

1. inner eye edge parallel (photo 4)
2. second discoidal cell front wing without sag (photo 5)
3. thorns on shin 3 equal in length and spacing (photo 2, 3)
4. front pronotum rounded (photo 2, 4)
5. first abdominal segment not petiolate (photo 2)
6. shin 3 dorsally with scales, ventrally seen sawtoothed (photo 2, 3)
7. tip radial cell pointed (photo 5)
8. propodeum hairless and smooth (photo 2)
9. dark pigmented frontwing with a bright spot at the tip (photo 1, 3, 4)
10. first tergites red (photo 2)
11. claw with side tooth closely to the end tooth and equal in size (photo 6)
12. antennal members slender, members 5 to 8 at least 2,5x longer then wide (photo 1, 3)
