So far, the host plants reported are Timonius wallichianus (Silver Timon) and various plant species from the genus Uncaria. Indeed, my first caterpillar was sighted on a Timonius wallichianus. However, the second one seen in December 2019 was found on a Guettarda speciosa (Beach Gardenia) tree located in the same park where I saw the first caterpillar several years back. In fact, there were at least 2 of them on the tree in the later sighting.
