Yes if its like other flies, they have loose pupae and I expect it will fall to the ground. I am surprised that I never notice other larvae since the hoverflies are common.

I discovered this larva is a hoverfly

Argy; my Chinese translation app. couldn't find a meaning for it so its possibly purely aesthetic. I thought this was a caterpillar but there were too many anomalies. An expert on flickr ID'd it for me as a fly.
