Passi Sapphire being Eaten at Night
I can't figure out what's eating my Passi Sapphire; it only happens at night; and whatever is eating it only eats the top newer leaves; every morning I notice it's eaten something else; usually off the very top leaf or the one under it; and it's not like it takes one bite; it will sometimes eat almost a whole part of a 3 part leaf; only leaving 2 parts of the leaf. and when it eats the still closed leaf it's actually eating both sides at the same time. This morning I noticed not only did it eat one side of a new leaf it ate a hole right through the center of a Bracht; I thought it was weird that it didn't start at the edge; there is a just a hole in the center of a large Bracht.
This plant is 6 ft high on a trellis; now from everything I read if it was a beetle that lives under the soil they eat the bottom leaves; whatever this is only eats the top new leaves and has been since the plant was only 2 ft. tall. I can't even find one single bug on my plant. Anyone have a suggestion? are bugs smart enough to fly to the same plant for a meal every night; because whatever it is dosen't seem to be living on the plant; well not that I can see anyway.
Thanks So much for any advice; it's now 12:30 am and I am going out to look right now to see if I can catch the culprit. I figure I will check every 1/2hr until I go to sleep. What we won't do for our Passi's.
