Zoo Stock Species and the Red List
Zoo Stock Species and the Red List
Zoo Stock
This indicates that the species is included in the Second Zoo Stock Plan, which was formulated by the Tokyo Metropolitan Government in 2018. The plan sets goals for the next 10 years in three areas: "species conservation," "contribution to wildlife conservation," and "environmental education and conservation awareness." 124 animal species are included.
What is the Red List?
Based on scientific research, this is a list of wildlife classified by rank (category) indicating the degree of risk of extinction.
Livng Things Encyclopedia shows the categories (mainland and islands) assessed by the IUCN (International Union for Conservation of Nature) at the global level, the Ministry of the Environment for Japan, and the Tokyo Metropolitan Government for Tokyo.
The higher the category in each table, the higher the risk of extinction, and CR, EN, and VU are the three categories known as "endangered species." In Tokyo, species that are not at the NT (near threatened) level but are relatively rare are considered "species of concern."

Heike Firefly
Luciola lateralis
Heike Firefly
Luciola lateralis
Its forewings are black, its prothorax is red with a black vertical stripe in the center. It resembles Genji Firefly but is smaller and has a different pattern on its prothorax. It lays eggs on moss or grass stems near water. The larvae are aquatic and live mainly in stagnant water areas such as marshes and rice paddies, feeding on snails such as Lymnaea stagnalis. When they grow, the larvae come ashore and pupate in the soil. Adults emerge from early summer to summer and have a light-emitting organ in their abdomen.
