What is this red thing?

Hi everyone I'm digging out an area of turf and I keep coming across little red things in the soil.
They look like red buds but I don't know whether it's a plant seed, insect grub or what. Should I leave them there, bin them, destroy them while wearing a hazmat suit...?
Thanks!

 

It looks like a moth or butterfly chrysalis not sure which though.... Generally they are attached to the stems of flowers, shrubs, veg etc. have you cut anything down recently that they could have fallen off?

 

It's probably a Moth Chrysalis, many types spend this stage of their life underground.

 

Thanks all and thanks @MarleyFarley for the helpful link. They were a good 3" underground, hence my puzzlement! As I unearth them, should I move them to a secluded corner of the garden and leave them above ground, or re-bury them in said corner? I don't want to kill them by doing the wrong thing...
