Sundays in this part of Peckham used to be really quiet – you’d be lucky to see anyone walking down the road. For any sign of activity you had to go to the bustling and colourful Rye Lane with its God hawkers, the endless queues in Primark and the greengrocers overflowing with bowls of vegetables for £1. Nowadays Bellenden Road is packed with upmarket shoppers, diners, drinkers and people wandering around with their heads stuck in estate agent literature, vying for space on the pavement. The population has exploded – do these people live here or are they on day-trips from elsewhere, having read in the Evening Standard that Peckham is the cool place to be?
A less visible population explosion in Peckham has been that of the Southern green shield bug – the unusually hot weather has created the perfect conditions for them to thrive. A recent immigrant to the UK from Africa, Nezara viridula arrived via the route of imported vegetables. Indeed, you may find them living happily on your broad beans or pea pods. In Warwick Gardens they tend to favour the blackberry bushes. The adults can be identifiable from its cousin, the Common green shield bug Palomena prasina, by 3-5 white dots along the front edge of the scutellum. The nymphs, however, are much more colourful, making you wonder how something so striking can morph into a rather bland looking bug.
Usually I only see one or two Southern green shield bugs each year – a somewhat uncommon sighting. But this year the nymphs are everywhere! Uploads on Flickr are plentiful, cropping up on Twitter with queries as to whether they are ‘ladybirds in fancy jackets’, and they have been recorded in Jersey for the first time. I like shield bug nymphs. They look so small and vulnerable but somewhat earnest as they get to grips with working out how to live in this world. Bunched together for the first few days after hatching they mill about before braving their independence and venturing further afield by themselves, usually down a plant stalk. Though the 37 Nezara viridula nymphs that hatched on the lavender bush in a front garden in Choumert Road opted to stay together after sussing out that ‘walking down the stalk’ meant landing on tarmac. Another large batch hatched on the bindweed in Warwick Gardens last week, looking like little black shiny beads glistening in the sun, and dispersed into the bramble bushes making them hard to spot. But we did find one – Paul Brock, author of the fabulous new book A comprehensive guide to the Insects of Britain & Ireland, who was visiting the park, scooped it up into a pot and whisked it away to raise in comparative luxury in the New Forest. We wish ‘Warwick’ well!
