准确的物种识别是记录生态数据的基础。然而，通过视觉正确识别生物体的能力很少受到质疑。我们调查了专家和非专家在识别大黄蜂方面的比较，大黄蜂是一群备受关注的昆虫。专家和非专家被问及两个并发的大黄蜂图像是否描绘了相同或两个不同的物种。总体准确率低于 60%，专家和非专家的准确率相当。然而，当重复相同的图像时，专家们的答案更加一致，并且在给出明确的答案时更加谨慎。我们的研究结果表明，使用现场指南中的图像正确识别大黄蜂是很困难的。在解释物种数据时，无论这些数据是否由专家收集，都需要考虑到此类错误率。我们建议，对专家和非专家如何进行观察的调查应纳入研究设计，并可用于改进物种识别培训。
Accurate species identification is fundamental when recording ecological data. However, the ability to correctly identify organisms visually is rarely questioned. We investigated how experts and non-experts compared in the identification of bumblebees, a group of insects of considerable conservation concern. Experts and non-experts were asked whether two concurrent bumblebee images depicted the same or two different species. Overall accuracy was below 60% and comparable for experts and non-experts. However, experts were more consistent in their answers when the same images were repeated, and more cautious in committing to a definitive answer. Our findings demonstrate the difficulty of correctly identifying bumblebees using images from field guides. Such error rates need to be accounted for when interpreting species data, whether or not they have been collected by experts. We suggest that investigation of how experts and non-experts make observations should be incorporated into study design, and could be used to improve training in species identification.
