Habitat Preferences of Treble brown spot Through Different Life Stages
The early larval stage of treble brown spot often resides on the underside of leaves of its host plants, making it a likely place to start the search. As the larvae mature, they can be found on the edges of leaves, where they feed and are slightly more visible. Pupation typically occurs in concealed areas such as under bark or in leaf litter at the base of the host plants, so searching these nooks would be a prudent approach. Adults are nocturnal and frequently encountered on or near the host plants where they mate and lay eggs. They can also be attracted to light sources at night, which provides an additional method for locating them.
