1.) As the spike grew, each leaf on the spike which surrounds the spike
itself has browned and looks deadish.

2.) During the day I see no bugs on the Vanda. Although at night, I
have been seeing (each night) one or two decently large green leaf
looking bugs which like to hang out on the spike. I have watched them
carefully and they hardly move and do not appear to be eating anything
or damaging the Vanda. This is the kind of tropical bug which looks
like a bright green leaf and just tries to blend in. Not sure how
dangerous this bug is for the orchid.
