Some insects of Singapore

Butterfly (?) on African Butterfly bush or "Oxford & Cambridge" (Light & dark blue flowers?)
 in Singapore's fabulous Botanic garden, where the heat was oppressive and the mosquitoes irritating -- but worth it.  Two days were not enough to see all there is here.  This butterfly clearly plays no part in pollination.  But...

this inch-long flying beetle should have done so.

South-east Asia's equivalent of the UK's female common blue butterfly?

Dozens of different species of damselflies and dragonflies are in the garden.

The sun is so intense that these insects rest with their abdomen in a vertical position to minimise the body area exposed to the sun.
