Resumen:
The degree of darkening of the gonopophyses in females final instar (F-0) larvae of Cordulogaster boltonii (Donovan) (Golden-ringed Dragonfly) is compared with the four stages (here referred to as 1 - 4) of metamorphosis described by Ferreras-Romero & Corbet (1999) in this species. There is a reasonable degree of correlation, with larvae showing no darkening of the gonopophyses falling mainly stages 1 and 2, whereas those with no more tan 25% of darkening fall almost exclusively into stages 3 and 4. The method described in the current study is a simple method for determining the stage of metamorphosis but it is suggested that, for maxium accuracy, both methods should be used.
