Aphids generally congregate on the new growth and flower buds so look for populations there. They also exude a sticky substance called honeydew when they feed so you may see a shiny substance on the tops of the leaves. This substance can eventually weather and turn black (called sooty mold). If you see any of these signs, aphids are at work. Crape myrtles develop flowers on the new growth of the season so the best time to prune is in the very early spring. You can trim several inches off all over or you can selectively shorten specific branches. After the flowers are spent you can prune your crape myrtle back again and it will respond with new growth and a second flush of flowers later in the summer. Hope this answers all your questions.
