Jewel beetles might be attracted to certain types of baits or lures that contain chemical attractants, such as pheromones, or natural plant volatiles that mimic the scents of their host trees. However, the specificity of the trap food would largely depend on the particular species and their known preferences.

The larvae of jewel beetles typically thrive under the bark of stone fruit trees like cherries, peaches, and plums, where they carve extensive galleries while feeding on the inner wood. Pupation also occurs within these areas, often within the last larval gallery. For adults, they are commonly found on the leaves and bark of these trees during the late spring and summer, where they feed and mate. To find them, one must scrutinize the host trees’ bark and leaves, paying close attention to the presence of exit holes or sawdust that indicates larvae or inspecting for adult jewel beetles on the foliage and stems during their active periods.

To find jewel beetles, the most suitable time would typically be during their active periods, which often corresponds to warmer months, especially spring and summer. This is when adults are likely to be breeding and laying eggs, and when larvae and pupae are developing.

The preferable weather conditions for finding jewel beetles would include warm, dry days, as high humidity or rain can reduce activity levels and make some life stages more difficult to observe. Optimal temperatures and weather conditions would vary based on the specific habitat and geographic location of the species.
