Sap-sucking dendro-killer, qu'est-ce que c'est?

[PragmaticOrchidGrower]

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!
