design on leaves: This RaanJaai creeper in my garden. I have noted that there appears some design on the leaves and was wondering what is it due to ? I have also posted the picture of its flower. It has no fragrance. The creeper grows very rapidly.

Looks like damage by leaf mining insects. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta) and flies (Diptera), though some beetles and wasps also exhibit this behavior.

Yes, some insects cause such markings on leaves of plants. Though I have no idea which insect causes it.

There is a larva inside below the epidermal layer eating while moving and making tunnels :).
Never saw it coming out.

There is an insect larvae living below epidermis and it travels inside eating and making tunnels :P… Those lines are actually its path.

Flowers look like Thunbergia fragrans and as it is scentless, so it matches with sweet clock vine but leaves look different. So m nt so sure.

the Larvae of Agromyzidae, also known as leaf-miner flies (minierfliege in german) is responsible for making these “designs”. http://en.wikipedia.org/wiki/Agromyzidae
I have a few fotos of some beautiful designs, will upload, when i have more time. I normally pluck the leaves and burn them or throw them away, not on kompost.
Till then watch some here:

After going through the links I understood that these larvae live a protected life within the tissues of the leaf and also at the following http://en.wikipedia.org/wiki/Leaf_miner that
The precise pattern formed by the feeding tunnel is very often diagnostic for which kind of insect is responsible, sometimes even to genus level. Interesting how Nature is!!
