Emergence is staggered and starts on the prairies about the third week in June and the beetles disappear by mid August. Both dates are about 10 days earlier than in A. cwzalinai. The adults aggregate strongly, often on certain plants in a stand and often feed on the lower leaves by scraping the upper surface. Also, they appear to thermoregulate by resting in the sun on cold days and moving into the shade of lower leaves on hot days. The adults are considerably more active than the other species.
Some populations are short-winged, although they can still fly and others in Europe are wingless.
The significance of this is not known. Occurs from the Caucasus to central Europe. Collected from E. esula and E. virgata in Yugoslavia, Hungary and subsequently Hungary via North Dakota. Screened by CABI Biosience with Spurge Consortium funds. No attack of North American spurges has been recorded.
