I have had no problems with boring insects on coelogyne. Maybe just a one-off incident. The plant certainly looks like rochussenii from the picture. Tall tapered at the top with 2 leaves that are rounded at the ends. If it is not rochussenii, then might be dayana/tomentosa, which has a similar habit, but often larger. Rochussenii is one of the few coelogynes that can bloom without artificial cooling in the lowlands.
