They occur in both bare and sunny locations, where it is often the first dragonfly to colonise new habitats such as newly created ponds, and well vegetated ponds. L. depressa are often seen away from water as the adults are very mobile and undergo a period of maturation away from water after emergence. The adults are also migratory.
The larvae develop within 38 to 65 days, [17] which allows this migrant dragonfly to reproduce in temporary waters or even in swimming pools. [18] However, the larvae seem to be very sensitive to temperature. [19] The life expectancy is not known and because of their high mobility it is almost impossible to determine.
Over the course of their adult lives the green of the male is gradually transformed into a duller shade of blue and finally a powdery bluish-grey. The wings are distinctively veined and have dark margins near the apices. [2] The length of this dragonfly is 36 to 48 mm (1.4 to 1.9 in). [3]
