Tiny insect

Description:

It was like a teeny-tiny drop of molten gold and melted chocolate on a Hollyhock leaf. That is my index finger for size comparison.

Habitat:

Urban, office garden. I initially mistook it for a tiny yellow leaf that had dropped from the Delonix regia tree above but the yellow colour was NOT that of a dead leaflet...it was the colour of molten gold. When I came too close it jumped backwards and disappeared maybe over my shoulders...I had not thought it would move in back-gear!

Notes:

Can anyone help me ID this? Please.
