A local grower was surprised yesterday morning by the huge bug infestation depicted in the photos below suddenly appearing in his berry field.
Photo 1: A mass of false chinch bugs crawling up a support post.

However, these bugs are “false chinch bugs” and while pretty scary, they do not damage berry fruit and in fact will very likely either die out or move on out in a few days. These bugs are usually associated with weedy fields or pastures that contain the mustards they prefer to feed on. As with most of these cases in our area around this time of year, a nearby field or meadow has been disturbed, usually mowed, and they end up migrating to an adjacent field.
So, if any others of our readers are seeing this, it’s just a signal to keep calm and carry on.

And of course the UC IPM guidelines have excellent information on it as well:
