it is likely to be these insects. Katydids are from the locust family.
Citrus is one of their plants of choice devouring buds, leaves
They are hard insects
to catch because they are green and blend in with the foliage. They
are nocturnal, flying at night, which will explain why you haven't
seen any (or only one). They shelter in long grass, so remove or
cut down any long grass where they like to hide.
Organic controls you
could try plant calendula as a barrier; horehound around
your citrus as a deterrent; spray with garlic oil as a repellent.
Neem Oil may be effective in disrupting insect growth. Whichever
method of control you choose, you will need to repeat applications
at regular intervals.
