This bug is not a lily pest. It is the brown marmorated stink bug Halyomorpha halys (BMSB), a native of Korea that has been ravaging crops in the eastern US for the past several years. It has recently become established in Ontario, around Hamilton. The photo was taken by our Swiss biocontrol colleague, Dr. Tim Haye, who is mapping the distribution in Europe where the bug is also invading (the site is in German, but Google will provide an entertaining translation).
In addition to its impact on crops and garden plants, the BMSB is a nuisance in the fall when it invades homes looking for places to spend the winter.
Tracking this pest is essential to developing an effective management plan. The Ontario Ministry of Agriculture and Food asks that anyone who believes they have found this bug contact them at 1-877-424-1300 or ag.info.omafra@ontario.ca . Specimens and high quality photos are essential since there are native stink bugs that look similar. You are also welcome to upload photos using my Report an Infestation page.
