Wasp laying eggs in psyllid galls

Braconidae (Family) Callibracon sp.

Description:

Gall forming scale insects produce protective elongated galls but the wasp has a suitably elongated ovipositor.

Habitat:

Galls are sometimes prolific on mature gum trees. The wasps are regular visitors.

Notes:

The last pic taken 24 May 2012 of a suspected developing larva of the wasp.

Jemma, the last two pics are a wasp larva. They are inside many of the galls. It has eaten the psyllid bug and is soon to pupate. The bug looks like this http://www.projectnoah.org/spottings/869... or this http://www.projectnoah.org/spottings/217... ,

So Martini,if you open the gall up,would you find Wasp eggs and the nymphs of the scale insect inside the gall?

Thanks John La Salle for the correction. I agree this is a (family) braconidae wasp but I just saw the long ovipositor and made an assumption. Both however are the same Superfamily Ichneumonoidea - Braconids and Ichneumons

This is a fantastic series of pictures. I think that the wasp is a Braconidae (not Ichneumonidae).

I have added a pic taken today of the developing parasitic wasp larva inside the gall.
