2011年在苗栗縣銅鑼鄉發現方翅網椿取食為害杭菊（＂Chrysanthemum morifolium＂ Ramat.），使葉片產生白斑及其黑色排泄物影響植株生長及菊花產量，經鑑定為墨里尼方翅網椿（＂Corythucha morrilli＂ Osborn and Drake），本文為該蟲在臺灣首次發生記錄。在定溫28℃下，觀察本種方翅網椿飼以咸豐草（＂Bidens pilosa＂ L.）生活史，卵期9日，幼蟲期9.8日，成蟲平均壽命17.8日。由於本種網椿主要寄主菊科植物在臺分布廣，未來是否擴大為害至其他經濟作物值得關注。

In 2011 the Morrill lace bug, ＂Corythucha morrilli＂ Osborn and Drake, a pest, was found on ＂Chrysanthemum morifolium＂ in Tongluo, Miaoli County, Taiwan. White spots and black feces resulting from their feeding behavior on leaves affects plant growth and flower production. This species was first recorded from Taiwan. At 28oC, the developmental time of both egg and nymph on Bidens pilosa L. lasted 9 and 9.8 days on average. The average longevity of an adult is 17.8 days. Based on the main host plants of ＂C. morrilli＂, various species of ＂Compositae＂, are common in Taiwan, its expansion into other cultivated crops caused damage is worth of future attention.
