<b>Meta Data</b> The pan trap technique was done in this study to compare the number of insects found on different colours of bowls in both the grassland and woodlot due to the attraction of the insects to certain colours. This study began at 3:25pm in the grasslands and woodlots of York University Keele campus located at York Blvd. and Keele St (43.7 degrees north, 75.9 degrees West). Weather conditions of the grassland and woodlot were partly cloudy, partly sunny and windy at a temperature of 21 degrees Celsius. In this study 4 yellow, 3 blue and 3 white bowls were randomly placed in the grassland and wood lot, for a total sample number of 20. Soapy water was poured into each bowl until each bowl was completely filled. At 4:20pm, the number of taxonomic units (measured in rtus) and the number of insects in each of the bowls for each colour were counted by observation and recorded for the grassland and the woodlot. Overall, the whole experiment took 55 minutes. The location where the bowls were placed were categorical variables as the 2 locations used were the grassland and woodlot. The continuous data used in the experiment were the number of insects recorded as well as the taxonomic units found (in rtus), which indicated the number of species found. It was hypothesized that the brighter the colour of the bowl, the higher the number of insects found. In other words, more insects will be attracted to the yellow and white bowls in both the grassland and woodlot compared to the blue bowls.

<b>元数据</b> 本研究采用盘诱法（pan trap technique），鉴于昆虫对特定颜色存在趋性，对比草原与林地生境中不同颜色诱捕碗的诱虫数量。本实验于当日15:25在约克大学基尔校区（York Blvd.与Keele St交汇处，北纬43.7°，西经75.9°）的草原与林地生境中启动。实验期间，两处生境的天气状况为晴阴相间且伴有大风，环境温度为21℃。本研究共制备黄色、蓝色、白色诱碗各4、3、3个，将其随机布置于草原与林地生境中，总样本量为20。随后向每个诱碗注入肥皂水至完全装满。当日16:20，研究人员通过目视计数，分别统计并记录两处生境中各颜色诱碗内的昆虫数量与分类单元（以rtus为计量单位）的数量。整场实验总耗时55分钟。诱碗布置的生境类型为分类变量，本实验选取的两类生境分别为草原与林地。本实验采用的连续型数据包括记录的昆虫数量以及测得的分类单元（以rtus为计量单位），该指标可反映样地内的物种丰富度。本研究提出如下假说：诱碗颜色越鲜亮，其诱集到的昆虫数量越多。换言之，相较于蓝色诱碗，草原与林地生境中的黄色与白色诱碗将吸引更多昆虫。
