What's That Bug? does not endorse extermination

Bug identification
May 31, 2010
I noticed these guys on my rose today. They hop and have very long antennae. It was late afternoon and they may have been searching for aphids. I only notice them on the dark colored roses. I live in Lodi, CA (Central Valley)

Scudder's Bush Katydid Nymph

Hi Mary,
This is an immature Scudder’s Bush Katydid.  Winged adults look like green grasshoppers with long antennae.  Katydids eat leaves, and we find that in our own Southern California garden, they like nibbling on rose petals.  They never get plentiful enough to be a problem, and we tolerate the Scudder’s Bush Katydids because they are such interesting creatures.

Thanks Daniel.  Yes, I read that they eat citrus but I have none on my orange or lemon here in the CA Central Valley.  They’re just on the roses.  I find them fascinating as well.  I love the antennae.  Do they eat aphids or are they herbivores?

Hi again Mary,
From all we have read, they are strictly phytophagous, feeding solely on plants, despite that numerous Katydids are predatory or at least omnivorous.

    Katydids are primarily leaf-eaters, but they also sometimes eat dead insects, insect eggs or slow-moving insects like aphids. I live in Northern California and have witnessed them feeding on aphids.
