Hoverfly on tomorilla

I bought the plant at a plant sale and then discovered it needs 2 to pollinate it reliably. The hoverflies like it and I've been trying the brush technique but no signs of fruit so far.
Did a bit of volunteering work at the ponds this afternoon (removing himalayan balsam) and then went to the funeral of a 101 yr-old who had been our oldest church menber and still attended until about 3 weeks before she died. A remarkable and godly lady.
Now off to a church leaders' meeting.
