Data from: Predator-prey interactions between shell-boring beetle larvae and rock-dwelling land snails

Drilus beetle larvae (Coleoptera: Elateridae) are specialized predators of land snails. Here, we describe various aspects of the predator-prey interactions between multiple Drilus species attacking multiple Albinaria (Gastropoda: Clausiliidae) species in Greece. We observe that Drilus species may be facultative or obligate Albinaria-specialists. We map geographically varying predation rates in Crete, where on average 24% of empty shells carry fatal Drilus bore holes. We also provide first-hand observations and video-footage of prey entry and exit strategies of the Drilus larvae, and evaluate the potential mutual evolutionary impacts. We find limited evidence for an effect of shell features and snail behavioral traits on inter- and intra-specifically differing predation rates. We also find that Drilus predators adjust their predation behavior based on specific shell traits of the prey. In conclusion, we suggest that, with these baseline data, this interesting predator-prey system will be available for further, detailed more evolutionary ecology studies.

The data package contains three datasets:
- Data Collection Codes
Collection details pertaining to the Albinaria samples, some containing Drilus laevae or adult, that were used in this study

- Data Predation Crete
This file provides information on the Cretan Albinaria collection samples used for producing the map of Drilus predation pressure. The samples without taxon identifiers were studied by Francisco W. Welter-Schultes and derived from the Haus der Natur, Cismar. The other samples were studied by Ruth F. Castillo Cajas and derived from the collection of Naturalis Biodiversity Center, Leiden.
