PROBLEM TO BE SOLVED: To provide a management method for a firefly biotope in which an escape place enabling firefly larvae to escape from the light of the lighting is provided on the bottom of a waterway, and thereby light restriction measures can be avoided in the period when the firefly larvae grow in the waterway, consequently a problem on the crime prevention due to restriction of a light through four seasons or the problem of difficulty to obtain understanding of local residents when performing traffic regulation through the four seasons can be improved.SOLUTION: A management method is provided for a firefly biotope 1 that has a waterway 3 to make firefly larvae 10 grow in a place lighted up by outdoor illumination at night. The management method is characterized in that an escape place enabling the firefly larvae to escape from the light of the lighting is provided on the bottom of the waterway 3, light restriction measures for restricting the light of the lighting are not performed in the period when the firefly larvae 10 grow in the waterway 3, and the light restriction measures are conducted in the period from when the firefly larvae 10 come out from the waterway to pupate till when firefly imagines are active.SELECTED DRAWING: Figure 1 【課題】水路の水底に蛍の幼虫が照明の光から退避可能な退避場所を設けることで、蛍の幼虫が水路において生育する時期において光制限対策を行わないようにして、四季を通じて灯りを制限することによる防犯上の面等での問題や、四季を通じて交通規制を行う場合に周辺住民の理解を得ることが難しいという問題等を改善できる蛍ビオトープの管理方法の提供。【解決手段】夜間において屋外の照明に照らされる場所に蛍の幼虫１０を生育させるための水路３を有した蛍ビオトープ１の管理方法であって、水路３の水底に蛍の幼虫が照明の光から退避可能な退避場所を設け、蛍の幼虫１０が水路３において生育する時期においては、照明の光を制限する光制限対策を行わずに、蛍の幼虫１０が水路から上陸して蛹化する時期から蛍の成虫が活動を行う時期においては、光制限対策を行うことを特徴とする。【選択図】図１
