What kind of insect is yellow with black spots, about an inch in length and three-quarters of an inch in width

Question

One of the trees in my garden has about 20 of these sitting on it's leaves. They have just started appearing. I cannot see any leaf damage yet, but I am worried that their numbers seem to be increasing. I can send you a photograph if you mail me.

Answer 1

"Striped Cucmber Beetle, Spotted Cucumber Beetle: Chewing insect 1/5-inch long. Yellow beetle with black spots or stripes on back. Treat when seedlings emerge. Treat entire planting at five-day intervals, as needed. Use Rotenone or Sevin. Spray or dust toward evening when bees are not pollinating. Sevin may kill bees when applied between 10 a.m. and 2 p.m. To avoid injury to tender foliage, do not apply when rain or humidity is expected during the next two days."

This sounds similar to what you described, but much smaller. Maybe they come from the same family? I doubt having all those bugs on your tree could be a good thing.
