I have recently met the Original Poster and he is a very enthusiastic young entomologist who should be encouraged. If I may comment to basquesteve , I think it is a grave mistake to slap people down, without knowing anything about them, for collecting ('killing') specimens- that is a really good way to make sure we are the last generation of entomologists.
You say it is a dead wasp- maybe that's good enough for you, but many people would prefer a more definitive identification, and when dealing with a family (Ichneumonidae) with 60,000 described species (and tens of thousands of undescribed no doubt), differentiating between them all very usually requires critical examination of a specimen. The poster has now shown the specimen to an expert at NHM, and hopefully an identification is forthcoming (but only because he had the presence of mind to collect a voucher specimen).
The wasp emerged from a pupa of an Atlas Moth which was supposedly bred stock; this is interesting for two reasons. Firstly, it is a concrete host record, evidence that this is a parasitoid of a charismatic giant moth. Secondly it is evidence that the atlas moth larvae were wild collected, or at least open reared within their native range (i.e accessible to native parasitoids), which teaches us something about the sources of the pupae available on the market for the pet trade. Both these things are of interest to someone, and so knowledge is generated from this specimen having been collected.
I admit to being very concerned about the next generation of collectors/ entomologists/ scientists. I believe casual 'anti-collecting' remarks can nip promising talent, which often grows up in a non-scientific environment anyhow, in the bud. I note that on other posts you have supported taxonomy and the importance of taxonomists- the one is a necessary part of the other...
