You're welcome Rick.
I think I need to spend some time rummaging through leaf litter! You are at a distinct advantage leaving leaves over winter, many predators hide under them. If you remove them you will not only be removing a safe haven for predators, you will also more than likely be killing them through shredding, burning or sending them to a recycling plant which in this country gets treated with heat.
Leaf litter also provides valuable winter protection for your plants and bulbs. In our very harsh winter 2010/11 which never rose above freezing for 7 weeks, with temperatures down to -17C, when tidying up in spring (if you can call it spring!) I found two apples buried under leaves which were not at all affected by frost!
Cameras have moved on so very quickly in the space of a few years, not long ago it would have been unthinkable to put 20mp on a DSLR let alone a prosumer or compact camera. You might get better results if you use spot focus and if the camera allows, also metering to match, that is unless you haven't already tried it. I find manual shooting to be so much better than auto for macro photography, auto does have it's uses for distance shots. For such a small bug you got some reasonable shots anyway, now you can see how much fun it is on the road to discovery!
