African rail
These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects, crabs and other small aquatic animals.
Aquatica hydrophila
The larvae are aquatic. They are unable to swim; they crawl at the bottom of water. The larvae prey on freshwater snails such as "Semisulcospira libertina" and "Thiara tuberculata". The adults produce green-yellow light and have been seen looking for mates near water. Artificial lights can attract males. There is probably one generation per year.
