Near more beehives, wild insects made fewer flower visits
In Paris, beetles, large solitary bees, and bumblebees visited flowers less where more hives were nearby.
The key idea
In Paris parks, more nearby hives went together with fewer visits from some wild insects, although the reason is unknown.
The study, in plain language
Researchers walked through Paris parks, counting which insects visited flowers, then compared those visits with the number of nearby hives. Across all wild insects, there were fewer visits where hive density was higher, even after accounting for the amount of floral resources.
The pattern was not the same for every group. Large solitary bees and beetles showed it within about 500 meters of hives, and bumblebees within about 1,000 meters. Honey bees also visited cultivated or managed plants more often, while wild visitors showed no such preference. Researchers did not measure whether hives competed with these insects or how their offspring fared; they only observed that the two measures were associated.
What they found
- Where more hives were nearby, wild insects as a whole made fewer flower visits.
- The pattern depended on the insect group and its distance from hives.
- Honey bees visited more managed plants, while wild visitors showed no such preference.
How they studied it
Researchers counted flower visits in five Paris green spaces in 2014 and seven sites during 2015 and 2016. They compared activity with registered hives nearby and with floral resources, without intervening.
What the study cannot show
- The design was correlational, covered the peak flowering season, and measured visitation activity. It does not establish causal competition or changes in reproductive success or population size.
Something to think about
Next time you see flowers in a park, notice who visits them besides honey bees. Are other insects there, and do they have places to nest nearby?
