The aim of this research is to analyze raptor predation on darkling beetles in the Mediterranean urban area of Rome. Urban Rome harbors a number of darkling beetle species, many of which are successful city-colonizing species. Both the kestrel and little owl prey on many soil dwelling darkling beetle species, especially in ruderal and built-up areas. In contrast, the tawny owl spends a great deal of time in wooded areas, preying on arboreal species. Kestrel predation on darkling beetles in a city-center ruderal site showed a decreasing diversity from summer to winter, in accordance to the termophilic preferences of such insects. In general, darkling beetles may represent a significant food source for urban kestrels in Mediterranean areas.

Abstract

The aim of this research is to analyze raptor predation on darkling beetles in the Mediterranean urban area of Rome. Urban Rome harbors a number of darkling beetle species, many of which are successful city-colonizing species. Both the kestrel and little owl prey on many soil dwelling darkling beetle species, especially in ruderal and built-up areas. In contrast, the tawny owl spends a great deal of time in wooded areas, preying on arboreal species. Kestrel predation on darkling beetles in a city-center ruderal site showed a decreasing diversity from summer to winter, in accordance to the termophilic preferences of such insects. In general, darkling beetles may represent a significant food source for urban kestrels in Mediterranean areas.
