Information
Ecological parameter: larval development cycleParameter group: life & body related parameters
Explanation:
The parameter indicates the season in which larval development is most intensive. It suggests a critical period of vulnerability to disturbances of the aquatic habitat and is closely connected with other life cycle parameters, such as emergence- and flight period or resistance form. A species' larval development cycle is not fixed; it can vary as specific habitat characteristics like thermal regime change with altitude and latitude.
