Idaea kendallaria

Pheromone traps are a common method for attracting adult idaea kendallaria, as these emulate the chemicals used to signal to potential mates. Additionally, light traps at night can be very effective due to the attraction idaea kendallaria has to bright sources of light. For caterpillar stages, assembling bait with host plant material can attract them.

The eggs of idaea kendallaria will primarily be found on the underside of host plant leaves. As caterpillars, idaea kendallaria are typically located on the foliage of the same plants where they blend in thanks to their camouflage. To find these caterpillars, careful inspection of the host plants during their active feeding period is necessary. Pupae of idaea kendallaria often hide in leaf litter or soil near the host plants, and adult idaea kendallaria rest on the bark of trees or on the leaves of the host or surrounding vegetation, blending in with their surroundings due to their cryptic coloration. While searching for idaea kendallaria at different life stages, one would inspect host plants for eggs and caterpillars, sift through leaf litter for pupae, and observe tree trunks and foliage for adults.

For adult idaea kendallaria, nighttime is the most effective time for observation as they are nocturnal and are attracted to light sources. For larval stages, daytime is suitable, especially late morning when the dew has evaporated and the sun warms up their environment.

Calm, warm and humid nights tend to be ideal for spotting adult idaea kendallaria since they prefer to be active in such conditions. Larvae are easier to find in moist conditions, although not in heavy rain, as they require high humidity for their development.
