Visitation rates of bee groups in videos in 2014

Visitation rates collected by in total 54 hours of video recording in 18 fields in 2014. Open Office Org Calc was used to create this data file. "no.visits" = number of visits by the corresponding species groups, "species" = species group {"bumble" = Bombus terrestris, B. lucorum, B. lapidarium; "halictid" = several Halictidae, mainly Lasioglossum species; "honey" = Apis mellifera}, "start.time" = starting time of the video at three different time periods (7:00 am, 8:30 am, 10:00 am).

本数据集源自2014年对18块野外样地开展的总计54小时视频录制所采集的访花频次数据。本数据文件通过Open Office Org Calc（开放文档表格套件）制作生成。其中，"no.visits"代表对应物种类群的访视次数；"species"代表物种类群，具体分组如下："bumble"指代熊蜂属类群，包含欧洲地熊蜂（Bombus terrestris）、光亮熊蜂（B. lucorum）及石熊蜂（B. lapidarium）；"halictid"指代多种隧蜂科（Halictidae）物种，主要以隧蜂属（Lasioglossum）类群为主；"honey"指代西方蜜蜂（Apis mellifera）；"start.time"代表视频录制的起始时间，涵盖三个固定时段：上午7:00、上午8:30及上午10:00。
