Conjoined swift

Suitable trap food would likely include the type of nectar plants that adult conjoined swift prefer, or host plants that caterpillars of conjoined swift feed on.

During its egg phase, conjoined swift is likely to be found on the underside of host plant leaves. As larvae, they typically inhabit the host plants they feed on, often constructing leaf shelters by binding leaves with silk. In the pupal stage, conjoined swift usually remains hidden within these shelters or other safe, concealed spots nearby their larval food sources. For observing the adult conjoined swift, searching near nectar-rich flowers in their habitat is recommended, as this is where they feed and are most active, especially in sunny areas.

The most suitable time to find conjoined swift would be during the day when the adult butterflies are most active, especially in the morning hours when they might be basking in the sun or feeding on nectar. For finding eggs or caterpillars, any time of day could work as long as the specific host plants are known and accessible.

Warm, sunny days with little to no wind are ideal for finding adult conjoined swift as they are more likely to be flying and feeding during such conditions. Overcast but still weather might make it easier to find resting adults or those nectaring. Moist conditions after rain could be suitable for finding caterpillars on host plants.
