This phys.org article says:

> Moths are more efficient pollinators than bees, oh and bramble is important.

The underlying paper is an easy enough read that you probably don't need phys.org: https://journals.plos.org/plosone/article?id=10.1371/journal...

It says:

- Many different species rely on bramble [e.g. raspberry, blackberry, etc...]

- Bramble fruits can grow twice as large if the flower was visited by multiple insects, which improves bramble's ability to support its many species

- Moths are an outsized contributor to the pollination of bramble, and therefore to supporting those many species

- So conservation efforts should focus on things that uniquely help moths, like limiting light pollution

Given the prevalence of pollinators that are hyper specialized to what they pollinate, I'm going to go out on a limb and say that general purpose pollinator efficiency is both a useless metric, and not what was studied here.
