This video does show a nice strip of flowering plants with pollinators.
But it doesn't tell you how long the field next to it has been treated with neonics.
This might well be the first year, so you would find all the bumbles still around.
Come back in a year or two and compare, you will be very lucky to see the same amount of wildlife.
Anybody can go out and visit field margins in areas that have had neonics applied for a few years, they will be very poor indeed.
Go and check it for yourself, don't just believe what is said on this forum!
