Four Angled Bean

Psophocarpus tetragonolobus


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.

Oh well done Lenny. Thank you so much.

I have only seen the caterpillar on this plant so far, although I have read that it is not a particularly fussy creature, with breeders able to raise the caterpillars on privet in the UK.

Here is an article that lists the plants for this species:
