Four lined plant bug
by: Moni

This is a four lined plant bug. Most plant bugs feed on plants sucking the juices out of the leaves leaving spots, scratch-like markings, blotches or other marks. The spots you see on this leaf are probably from this bug. If you look at it you can see a black dot in the center of each brown spot that is probably where the bug put its mouth parts in to suck out the surrounding juices. Some of the plant bugs inject a substance that kills the surrounding tissue.
Most of the damage by plant bugs does not look good but does not kill the plant. Organic control is mostly from beneficial insects like lady beetles, green lacewings, spiders, etc. You could also try Doug's favorite :-) - hose them off, but since the adults fly they will probably come back.
