Sap-sucking dendro-killer, qu'est-ce que c'est?
 
Something is killing our Dens! it seems to attach the young and thinner leaves first, but as we got a baby a few months ago we've sort of neglected our orchids and these bugs (or what ever they are) were allowed to feast :( It seems to not bother the dens too much as long as they got watered regularly, but the one that started having this problem has never re-bloomed.... Now most of the leaves are infested and I was hoping to save the keikis or new growth if I can only identify the pesky critter that is doing this to them. The Dens are NOIDs but they are pretty when they bloom and I like them, so pls help out!

Pictures added
 
sorry, you were too quick for me. I had to edit the pics before adding them here. Added pics of the damage done, it's a matter of 4 dens now, one (Berry Oda) already died :( (or we tossed it out as it was too far along)

I was thinking possibly spider mites or thrips. Here is a link that may be of interest.

I agree
 
Looks very much like Thrips :( Only issue now is to find something that is legal to sell in Norway that I can use to kill them....

Isopropyl alcohol usually kills many soft bodied insects.

true, but then I'd still have to fight the nymphs an pupae. I guess it will be a loosing battle to only get the grown up insects... I've googled a bit and it seems something called Conserve should do the trick on Trips. Anyone heard of it?? What remains to see is if I can buy it myself or if it needs to be a certified professional of some sort...
