Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
Gardener's request: I've just caught and identified what looks like a California Angle-wing Katydid. Is this insect destructive or should I just let it fly away?
(Microcentrum californicum)
Katydids can be damaging to a number of plants including trees, and they are frequently found in our area but are not of real concern to plant damage or nuisance unless you have a high population. So, with an assessment of your garden, I think if you would like to release it there should be no overall harm done!
Here is some more information from UC:

Congratulations on your interest in bugs!
