Acanthococcus azaleae
Azalea Bark Scale
Acanthococcus azaleae, commonly known as the azalea bark scale, is a felt scale insect in the family Eriococcidae. It is native to Asia and has been introduced to North America, Europe, and other regions through global trade. The species feeds on azaleas (Rhododendron spp.) and related ericaceous plants, forming white, felt-like coverings on bark. It was initially confused with the invasive crapemyrtle bark scale (Acanthococcus lagerstroemiae), which was first identified in Texas in 2004 and later determined to be a distinct species. The azalea bark scale produces honeydew that supports sooty mold growth and can cause branch dieback in heavy infestations.
Caloptilia
leaf cone moths, leaf blotch miner moths
Caloptilia is a genus of small moths in the family Gracillariidae, commonly known as leaf cone moths or leaf blotch miner moths. Larvae are leaf miners that typically feed internally on leaf tissue during early instars, then later instars roll or fold leaves into protective cones or shelters where they complete development and pupate. The genus contains numerous species, many of which are host-specific to particular tree or shrub genera. Several species have become economically significant as pests of ornamental and horticultural plants, including Caloptilia fraxinella on ash trees and Caloptilia azaleella on azaleas.
Darapsa choerilus
Azalea Sphinx

The species was first described by Pieter Cramer in 1779. Adults are medium-sized moths with a wingspan of 57–75 mm. Larvae feed on azalea (Rhododendron) and Viburnum species.
