Hi Angus,

A few notes:

1) the "Tachinid Fly sp." is probably a species in the genus  
Nowickia, likely either Nowickia algens (Wd.) or else Nowickia pilosa  
(Toth). The other possibility is a species in the genus Archytes,  
likely A. aterrimus (RD), but I think the former genus is more likely.

2) With respect to "Sawfly - Tenthredo sp." I agree with David  
McCorquodale and nafensler that this is a wasp. The banded  
appearance  doesn't resemble any species in the Tenthredinindae that  
we have in the Museum, nor does the overall habitus resemble the  
tenthredinids that I'm familiar with. I think it may be in another  
family of wasps.

3) The "Wasp - Astata sp." could be this genus (we have one specimen  
of Astata sp. here in the Museum determined by Larry Packer), but it  
also bears a resemblance to a Dryudella sp. (also determined by Larry  
Packer) so without knowing how to seperate these genera I would say  
that they are both possible (no specimens of Diploplectron in the  
collection).

Cheers!

Chris
