Identification of captured beetles In experiments 1 & 6, all captured beetles were identified to species and their sex was determined using taxonomic keys (Al Dhafer, 2009; Etzler, 2013; Johnson, 2002) and an identification guide for northwestern species found on agricultural land (Frank Etzler, unpublished). In experiments 2–5, all beetles were counted and sorted by genus until further species identification.

Identification of captured beetles Click beetles were identified to species using a taxonomic key (Becker, 1956). Specimens that were taxonomically ambiguous were identified solely based on genitalia characteristics. Specimens with missing genitalia or otherwise badly damaged were excluded from analysis. All beetles collected were identified to species.
