Non-honey bees

Today’s cartoon is a slightly changed version of one I posted on my Polish blog some time ago. I remembered about it after reading a paper entitled “Pesticides and habitat loss additively reduce wild bees in crop fields” by Anina Knauer et al. (2025). It is a huge analysis of data collected from nearly 700 crop fields, aiming to answer the question of how pesticide use and habitat loss impact bee numbers and species diversity.

Unsurprisingly, it turned out that both these factors have important effects on wild bees. But what was less expected, pesticides and availability of semi-natural habitat act additively. It means that, for example, pesticides aren’t less harmful if we provide the bees with more semi-natural habitat in places where they are used. To help bees, we must address both these issues.

It doesn’t mean that action aimed at solving one of the bees’ problems alone is useless. Every small step can help and is important to do. But we should not assume that solving only one problem is enough to save our pollinators.
