For thosea sinensis, typical food plants used in traps might include the leaves of the host plants that caterpillars of thosea sinensis consume.

The thosea sinensis eggs are typically laid on the underside of host leaves where they remain until hatching. Once hatched, the larvae can be found on leaves, often chewing on the edges or surface. Searching for them involves careful inspection of the host plants. Pupae typically affix themselves to twigs or in the crevices of bark, so one must examine the branches and trunk of potential host trees. Adults are nocturnal and rest during the day. Finding them involves checking around lights at night or searching for them on the trunks of trees where they may be camouflaged during the day.

The suitable time to find adult thosea sinensis would generally be at night since many Lepidoptera species are nocturnal and are attracted to light sources. Caterpillar stages may be found during the day on host plants.

Dry and warm conditions are often more suitable for observing adult thosea sinensis, as too much rain can deter them from being active. For caterpillars, moist conditions might be necessary as it supports the growth of their food plants.
