Quick Summary

A recent eight-year study by the UK Pollinator Monitoring Scheme shows that plants commonly considered "weeds" are crucial for pollinating insects. Common ivy leads in attractiveness with 22 insect visits per ten-minute observation, followed closely by hogweed and bramble flowers. Non-native buddleia attracts four times as many butterflies and moths compared to other high-scoring flowers. The study emphasizes the importance of these plants in supporting diverse pollinator populations amidst declines in hoverfly numbers.

Story summary

As of 2026-10-14, The Guardian reports that common urban plants often dismissed as "weeds" are crucial for pollinating insects. According to an eight-year study by the UK Pollinator Monitoring Scheme, common ivy is the most visited plant by bees and butterflies, receiving 22 insect visits per 10-minute count. Other popular plants include hogweed (20 visits), non-native buddleia (which attracts four times as many butterflies and moths compared to other high-scoring flowers), bramble, knapweeds, and thistles (each averaging around 14 visits). Jo Milborrow from Butterfly Conservation emphasizes the importance of ivy for breeding holly blue butterflies and providing nectar for commas and red admirals.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.

Narrative

Jo Milborrow, the butterfly monitoring officer for Butterfly Conservation, one of the partners in the pollinator monitoring scheme, said: “We already recommend ivy as a great plant to grow because it is an important resource for breeding holly blue butterflies and nectaring commas and red admirals, so the fact that this easy-to-grow native species is also the number one plant for pollinating insect visits is a fantastic discovery – we would recommend people to start growing ivy today!”

numbers → run → years
There was better news for solitary bees, which increased in one survey. asserted
which → be → survey
Honeybees, beetles and flies excluding hoverflies all increased in the survey, which covered mostly gardens, suggesting that these could be providing an important refuge for some pollinators. uncertain
these → exclude → pollinators
Martin Harvey, a volunteer coordinator at UKCEH, said volunteers could contribute counts via the Pollinator Monitoring Scheme website next year between April and September. uncertain
volunteers → say → April
“Participants often say how much they have enjoyed spending time counting pollinators,” he said, “and it is always fascinating to observe the close association between insects and flowers”. asserted
it → say → insects
