I am trying to find an ID for this vine plant, so that I can record it as a host plant for the caterpillar of acherontia lachensis. The plant is a vine and this is the fruit. Unfortunately, the caterpillars had eaten all the leaves.
Adjacent to a small stream. Altitude 1000m.
I know it is a big ask for an ID, but I will settle for any good Asian plant links and I will do the leg work myself – thanks.
