I have been letting some kurly kale go to seed for that seed.

I had noticed a build up of grey aphid, but had not time to deal with them.

Yesterday, I noticed something I had not seen before with grey aphids, the
presence of what could be 2 ypes of predator.

The first looked like a rather washed out wasp or hover fly. the colours
were darker and lighter grey in bands. When observed further, most seemed to
have died in the act of hanging on to the yellow flower. There seemed to be
two sizes of this maybe male/female. Or maybe larger and smaller (more like
a fly) of differenctent species.

On some kale heads, almost clear of grey aphids, there were masses of small
black beetles about 1.5 x 2 mm. in size. These were very willing to fly.

Does anyone know if these both predate the grey aphids ?
