The Sycamore Tussock Moth (''Halysidota harrisii'') is a species of moth of the Erebidae family. It is found in South-Eastern Canada, the Eastern parts of the United States (but not Florida) and North-Eastern Mexico. The wingspan is about 50 mm. The moth flies from May to June and from July to August depending on the location. The larvae feed on the American Sycamore tree (''Platanus occidentalis''). Unfortunately, an overpopulation of the insect can be damaging to sycamore trees. The ideal way to manage the moth and caterpillar populations is to foster a healthy bird population. The Sycamore Tussock Moth caterpillar has been known to cause urticaria (hives) to those who touch its hairs. This defense mechanism protects the caterpillar from potential predators. If you find a Sycamore Tussock Moth crawling on you, do not pick it up or swat at it. Use a folded piece of paper or stick to gently remove it. Acting aggressively toward the caterpillar increases the likelihood of exposure to those defensive hairs. Look but do not touch. ==External links== *(Species info ) *(Bug Guide ) * Immune response profiles after caterpillar exposure: a case report, J Inflamm Res. 2010; 3: 45–51. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3218733/ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Halysidota harrisii」の詳細全文を読む スポンサード リンク
