公民科学家有潜力在研究快速变化的瓢虫（瓢虫科）种群中发挥关键作用。我们使用来自三个以瓢虫为重点的公民科学项目的数据来检查从直接公民科学（未经验证而使用的数据）和经过验证的公民科学（经过训练有素的专家验证的观察结果）项目收集数据的成本和收益。与经核实的数据相比，通过直接公民科学整理的数据高估了物种丰富度和多样性值，从而影响了解释。使用公民科学家收集数据也影响了研究成本;我们的分析表明，经过验证的公民科学比传统科学更具成本效益（就每美元收集的数据而言）。通过直接公民科学收集更多样本的能力可能会弥补准确性的降低，这取决于收集的数据类型以及志愿者犯错误的类型和程度。
Citizen scientists have the potential to play a crucial role in the study of rapidly changing lady beetle (Coccinellidae) populations. We used data derived from three coccinellid-focused citizen-science programs to examine the costs and benefits of data collection from direct citizen-science (data used without verification) and verified citizen-science (observations verified by trained experts) programs. Data collated through direct citizen science overestimated species richness and diversity values in comparison to verified data, thereby influencing interpretation. The use of citizen scientists to collect data also influenced research costs; our analysis shows that verified citizen science was more cost effective than traditional science (in terms of data gathered per dollar). The ability to collect a greater number of samples through direct citizen science may compensate for reduced accuracy, depending on the type of data collected and the type(s) and extent of errors committed by volunteers.
