Whiteflies
Whitefly adults are very common on many outdoor different plants. At this time of year, they are unlikely to cause serious damage to temperate plants. The foliage is hardened off and deciduous plants are getting close to leaf drop anyway. Tropical plants, either still outdoors or in greenhouses, are susceptible to damage due to the constant growth characteristics of tropical plants.
