This is a multi-part message in MIME format. --Boundary_(ID_hjb6S6bBdYK0sttyj9D4nQ) Content-type: text/plain; charset=us-ascii Content-transfer-encoding: 7BIT Hi everyone, Since beetles have been a hot topic on the list I thought I'd pass this email from the eastern Ontario naturelist along. The sender lives in the Ottawa area. All the best, Lance =================================================================== I have not posted mention of lily beetles this week, but there has been some scientific interest in a phenomenon noted here recently. We have had a very heavy infestation this year, to the point where Linda and I have not been able to squish them in sufficient numbers to keep them from eating virtually all the leaves of the lilies up against the house. About ten days ago, I noted them eating a vine growing out from under a spruce tree ca 5m from the lilies. The vine was subsequently identified by Fred as solanum dulcamara, or nightshade, a toxic invasive. I passed this information on to Professor Naomi Cappuccino from Carleton University, who two years ago had visited us and who had one of her grad students study the beetles as a masters degree thesis, with many specimens coming from our garden that summer. This morning, Naomi and another student, Tonya, visited to take pictures and specimens. This is interesting to me because it may be a case of the beetle taking up toxins from the nightshade to use for its own defences; alternatively, it may be that the beetles are desperate for a food source now that the lilies have been laid waste, although no other species other than nightshade seems to have attracted the attention of the beetles to this extent.
