I cross-posted, basically (and I agree with "attract"). I posted in the d-box because I only wanted to give Veronika some options. I was cautious when it came to the verb (may be), but yes, there are very few examples.
The point about "approach" was that it really depends on the sentence (it sounds fine in the Guardian article).
As for visit (preferrably as a noun), here's the Botanical Society of the British Isles:
"Clearly pollinator visits to flowers of S. romanzoffiana during our time on Colonsay were infrequent."
https://archive.bsbi.org.uk/BSBINews106.pdfOr The London Beekeepers' Association:
"It is estimated that honey bees need to fly 55,000 miles and make 4 million visits to flowers to produce a single pot of honey."
http://www.lbka.org.uk/forage.htmlThe Telegraph:
"...the former detective who invented the technique, have now used it to analyse patterns of visits to flowers made by foraging bees."
