What insect is this? (Black body two orange lines in its back and six legs)
It's a larvae from a ladybird (or ladybug).  Judging by the stripe pattern it is a Common Spotted Ladybird (wiki: Harmonia conformis) and from the body shape &amp; size I'd also say 3rd instar.

The one you have photographed, and the one on flickr, are larval forms of the ladybug, just like when a catepillar becomes a butterfly, the ladybugs also have a larval stage in their life cycle which crawl around and look very different to the adult form.
