Caddisfly (Trichoptera) records from Britain (excluding Northern Ireland and Channel Islands) up to July 2024 from the National Trichoptera (Caddisfly) Recording Scheme

The Trichoptera dataset was assembled by the UK Trichoptera (Caddisfly) Recording Scheme. The scheme is linked to those for Mayflies and Stoneflies under the umbrella of the Riverfly Recording Schemes which is one of the Biological Records Centre family of schemes.

The data comes from a wide range of sources ranked in terms of contribution: volunteer recorders; statutory monitoring bodies, especially the Environment Agency; national and local entomological and natural history publications and ‘grey’ literature; museum collections; local record centres; consultants.

The principal aim of the Caddisfly Recording Scheme is to collate all available caddis records to produce comprehensive distribution maps and conservation reviews. Several of the data sets it contains are independently submitted to the NBN and an effort was made to exclude those from this download.

The data set contains duplicate records where the same record has arrived from different sources, e.g. as an entry in a collector’s notebook then as a collated list and possibly then as a published record.

The data base is only set up to take data at up to 8 figure grid reference resolution but more detailed data is available for a few records and can be requested from the scheme organiser.
Additional information about individual records is sometimes available and can be requested from the scheme organiser.

本毛翅目（Trichoptera）数据集由英国毛翅目（石蛾，Caddisfly）记录计划汇编而成。该计划隶属于河蝇记录计划（Riverfly Recording Schemes）体系，与蜉蝣（Mayflies）、石蝇（Stoneflies）的记录计划相互关联，而河蝇记录计划是生物记录中心（Biological Records Centre）旗下系列计划之一。

本数据集来源广泛，按贡献度排序依次为：志愿记录者、法定监测机构（尤以环境署（Environment Agency）为代表）、国家级与地方级昆虫学及自然史出版物、灰色文献（grey literature）、博物馆馆藏、地方记录中心以及咨询机构。

石蛾记录计划的核心目标是整合所有可获取的石蛾记录，以绘制全面的物种分布地图并开展保护评估。该数据集所包含的部分数据已独立提交至国家生物多样性网络（National Biodiversity Network，NBN），本次下载已尽力排除此类数据。

本数据集存在重复记录：同一记录可能通过多种渠道汇入，例如先以采集者笔记本条目形式提交，随后被整理入汇总列表，最终可能以出版物形式公开。

该数据库仅支持接收8位网格参考坐标分辨率的数据，但少量记录包含更精细的坐标信息，可向计划组织者申请获取。

部分单条记录的额外补充信息亦可向计划组织者申请获取。
