                                                                                   Life Cycle of  the
Dark Green Fritillary


This conical shaped egg measuring c.1.0 mm tall is yellow when first laid and develops purple bands in time.
It is deposited near to, or on,  violet  plants in sheltered places in July and August,  hatching in c.20 days.

The fully fed larva reaches c.38 mm in length.  Its body is velvety-black and speckled white especially on the 
dorsal surface.  There are dorsal and lateral branched black spines and a distinct row of  8 bright red spots 
along each side below the level of the spiracles.  Shiny black head.

The newly hatched larva  after eating its eggshell immediately goes into hibernation.  
It overwinters at the first instar among leaf  debris at the base of  its foodplant.  As soon as spring warmth 
arrives the tiny larva commences maturation and feeds on the fresh growth until it reaches full size about
late May.  This larval stage lasts from August to May or June.


Pupation takes place completely hidden in dense vegetation about late May and lasts for  3-4 weeks.  The pupa is  
suspended in a loosely constructed tent-like structure of spun leaves low down among vegetation.

The butterfly emerges from mid-June onwards and is on the wing until mid-September.  During this time 
feeding,  mating and ovipositing takes place.
