Bio data

In the last Meadow along The Three Trout Stream in Farrankelly you have a beautiful wetland meadow. After talking to the locals, I know that this field has never been sprayed or damaged by agrochemicals and is thus very important to our wildlife as a home and possibly a vestige to numerous rare insects and molluscs. Here is the Green shield bug eating Plantian as it rots or eating eggs or other insects that are soo small we cant see. Plantain is an amazing plant I find soo many insects using it for food including Clover mite (Bryobia praetiosa) on Buckthorn Plaintain.

In Europe, the bright green shield bugs appear in April or May, having hibernated as imagos during the winter. They fatten for a month and then mate in June. The imago’s coloration changes over the summer months from green to greenish browns even bronze, after which the life cycle will end. Mating is back-to-back. The female lays her eggs in hexagonal batches of 25 to 30, and a single female will lay three to four batches. After the eggs hatch, the green shield bug enter a larval stage (which is really their first nymphal stage) where, in general, they remain together in sibling communities. This is made possible by the excretion of an aggregation pheromone. In case of danger, another pheromone is released which causes dispersal. The larval stage is followed by four more nymphal stages as well as moulting between each one. The green shield bug displays different colouration during each nymphal stage, light brown, black or green-black, and in the final stage, the imago, is bright green with short wings. Usually the imago stage is reached in September, with hibernation occurring in November.
