This website is devoted to wireworm and click beetle research, with some focus on recent research

published by Drs. Bob Vernon and Wim van Herk and others, and on wireworm identification.



This is a personal website of W. van Herk; the website was not commissioned by Agriculture and Agri-Food Canada (AAFC).

1.     Introduction


Wireworms are the larval stage of click beetles (Coleoptera: Elateridae).  Some 9300 species of click beetles are described worldwide (Schneider et al. 2007), and Johnson (2003) lists 91 genera in the Nearctic region alone.  Bousquet (1991) lists 369 species known to Canada, the larvae of no more than 20-30 of which would most likely be considered pests (of wheat, corn, strawberry, potato, etc.). 


Some of the most important wireworm pest species in Canada and the USA include Agriotes obscurus, A. lineatus, and A. sputator; Limonius canus, L. californicus, L. agonus, and L. dibutans; Melanotus communis; Ctenicera destructor and C. pruinina; Hypnoidus abbreviatus and H. bicolor/nocturnus; and various Conoderus species.  Species such as Ctenicera cruciata (now known as Selatosomus cruciata) are pretty but not known to be pests. 


Knowing which wireworm species is dealing with is important as wireworm life histories and wireworm susceptibility to an insecticide varies among species.  However, accurate identification of wireworm species can be somewhat challenging as:

-        the larval form of most click beetle species is unknown (mostly because wireworms are hard to rear to adulthood in the lab, the larval stage often lasting 3-4 years),

-        good wireworm identification keys are scarce and usually limited to one genera or one geographical region; they also tend to be old and hence give obsolete names,

-        species are constantly being moved around from one genera to another (e.g. some Cryptohypnus species were moved to Hypolithus and then to Hypnoidus, and most Ctenicera species described by Glen 1950 have since been moved to other genera).  More on that below.


On this website we intend to give some information about wireworm identification, and provide an overview of some pertinent literature on wireworm biology and management.

4.     Wireworm identification


A little research into the classification of the Elateridae will likely lead to both confusion and frustration.  Depending on which author one consults (and whether the author focused on the adult or larval stage), the Elateridae may be subdivided into as few as 3 subfamilies (Stehr 1991) or as many as 18 (Lawrence and Newton 1995).  Johnson (2003) divides the Nearctic genera into 7 subfamilies.
