Ischnus alternator (Gravenhorst, 1829) View in CoL
Somewhat more common than the preceding species is I. alternator . It is easy to recognise by the basis of several white rings on the hind legs (tibiae basally, tarsi) and white tibial spurs. Sometimes the antennae are orange basally. Lastly, the first tergite of the metasoma basally has a distinct tooth laterally (SCHWARZ [2013], draft key). Our findings demonstrate it is very common in traps on open and more sandy grounds, presumably searching its hosts ( Tortricidae ).
First report for Belgium; confirmed in the Netherlands.
