Looks like Sapindus emarginatus or Soap fruit.

Thanks …. It does look like Sapindus emarginatus.

Leaflets 2-3 pairs, anthers apiculate

Request Tree ID 43 Bangalore – Is it Madhuca Indica?: Ulsoor, Bangalore

To me, it looks like Sapindus trifoliatus L. (= S. emarginatus Vahl) by its emarginate leaf tip. Both S. trifoliatus and S. laurifolia are hardly distinguishable from each other except by the leaf tip character.

There is record about the presence of Sapindus mukorossi which is available in Himalayas ans Nepal. this is also called soapnut only.

What is the insect on Sapindus Trifoliatus – South Indian Soapnut Tree?: I saw lots of them on a big tree on cubbon park as well as the smaller ones around my home.
They have come only after the fruits showed up.

It looks like mating bugs.

Shield bugs

---

If I Google for shield bugs (which are also called stink bugs) I don’t see that White patch.

Is this a symbiotic relationship?

---

Unless we can systematically understand both plant and bug benefit each others in sharing resources we cant say that there is symbiotic relationship.

Example the insect forages nectar from the flower that resulted in pollination or the bug takes any exudates and prevents pathogens and predators attacking the plant.

---

There are many varieties of the Stink/shield bugs. For a more accurate identification, you could post the bugs at insectindia at yahoogroups, where many knowledgeable persons would help you.

---

Might be a species belongs to the family Pentatomidae

---

Agreed. This is a Stinkbug / Shieldbug of Family Pentatomoidae, possibly a species of Tessaratoma.

---

I saw it on Sapindus emarginatus – Notched Leaf Soapnut
