abstract:Hoverflies, sometimes called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods.
Theflower-visitinghoverflyabundance at the low site is higher than that of the high site, whilethe species richness is lower than that at the high site.
Meanwhile Arctophila superbiens and Arctophila bombiformis, two other hoverfly species, each of which accurately resembles a particular bumblebee species, are restricted in distribution and rare.
