It is the middle of August and ever since the vote to leave the park there has been a quietness… not much is happening and many residents have decided to go some place else where they feel welcome. The social wasps are out and about, attracted by the ripening fruit in the orchard. But there is a wariness in the air as an article has to be invoked and everyone is waiting to see what happens next. Queen Vespula Vulgaris has started her nest in a loft in Lyndhurst Grove and already built up an impressive entourage of loyal workers. She is an incidental queen, put into power because her predecessor chose to fly off when the going got tough, having made a pigs ear out of the silly referendum. This new queen enjoys making life uncomfortable for insects: cracking down on the rights of free buzzing, a stiff policy on non-native species allowed in the park, and stinging anyone who isn’t a well-paid pollinator. She is snappily dressed, all yellow and black stripes, with a formidable weapon in her tail which she has already admitted she will use if threatened. She rules over a nest of conservative identikit workers who tend to her every need, except one who is a bit wayward, rather rude and untidy with no sense of tact who has insulted many insects in the park. For some bizarre reason he has been given the job of representing the nest.

Vespula vulgaris and Vespula germanica

On the other side of the park are the industrious German wasps. Though not big on presentation their nests are impressively constructed by a studious workforce, having honed their skills in engineering which are the envy of the hymenoptera world. Queen Vespula Germanica rules her realm in a somewhat christian and democratic way, often dealing with skirmishes that break out between neighbouring nests in her role as a de facto leader of a union which has grown so large no one quite knows who’s in charge. Identified by a 3-dot Merkel-Raute stamped on their faces, the workers are not best pleased with their queen and her ratings have plummeted. She will soon be up for election.

In the near future our queens will have to meet to discuss the Vulgar wasps leaving the park. The German wasps are understandably buzzed off as their dream of the union is beginning to fall apart. They will have to negotiate who has the rights to harvest the juice from the plums and pears, with access to the common orchard being the biggest concern, and who will have buzzing rights over annoying the humans at their picnics. There are worries about the open border policy, fearing swarms of hornets, forceably smoked out of Dulwich Park by the council a couple of years ago, could be given free access to Warwick Gardens. If it doesn’t go well the Vulgar wasps may be cast out, left with making a go of it alone with only the blackberries to trade with. What a mess.

Buggered off

Its the middle of July and Warwick Gardens is looking a bit worse for wear, reflecting the vibe of the country after voting to leave the EU. The foxes have flattened the foliage; the bindweed, with their delicate white trumpet flowers a foil for the hidden intentions of domination, has spread insidiously over the nettles and brambles suppressing any hope of freedom of growth; and the daisies are looking a bit weary with having to regrow after being constantly mowed down. The yarrow, hoping to host their annual festival of pollen and nectar, have popped up in an empty venue.

Red capsid bug

Last year this place was buzzing. It was noisy and full of life – a showcase of the sheer diversity of invertebrates in the park. But it seems that this year is one festival too many; the insects are preferring a more boutique ‘meadow-style’ festival offering a mélange of flowers and a more discerning flavour of nectar, sown especially to add colour and variety to bland parks. Everything is really quiet. The Roesel’s bush-crickets, normally hired to chirrup up business, chose to leave the park believing it was overrun with migrant species, a cynical lie perpetrated by unscrupulous anti-orthopterists; and the remaining grasshoppers have gone on strike, aghast that the crickets were lied to. The flies, patriotic and always up for a fight, are flitting around making nuisance for the non-natives. A few red capsid bugs are creeping around, anxious not to be mistaken for a Pokémon Go character, but all the while wishing that they could be found and appreciated as a real living thing. Even the mirid bugs got bored waiting for the party to start and just buggered off. And the weather hasn’t helped. A dull wet spring and cool temperatures have exacerbated and confused many residents about when and where to start a family. Its like nobody cares, exhausted at the changes around them.

The mottled shield bugs have had their lilac habitat ripped away by someone ‘wanting a better view of the park’, and having arrived in Peckham only a few years ago feel rather rejected. The hawthorn shield bugs, with their brightly coloured coats of majesty, have had their ancestral home savaged by cuts, the lower branches lopped off to make it cheaper to maintain. And the parent bugs and birch catkin bugs got ousted from their favourite independent tree in the multi-species part of the park, chopped down by someone ‘wanting more light in their garden’. They had to relocate to the big corporate birch trees on the other side of the park. Unfortunately it seems they didn’t ‘fit in’ as they have disappeared, leaving the planthoppers with no one to play with. Or, as this is the main constituency of the rather moderate birch shield bug, maybe the birch catkin bugs, with their left-wing ideals about ‘rights to live on the same tree – we share the same host plant’, were viewed as a threat to the stability of the community, fuelled by pedantic catkin politics, forcing a campaign to stop them taking over.

At least the green shield bugs, the hard-working bugs of the park with no obvious affiliation to any plant, are holding on. Those green shield bugs who everyone knows so well that they are prefixed with ‘common’ and generally taken for granted by the conservationists. The bugs who spend their days dutifully sap-supping, impervious to the strange weather we are having, almost neglected until someone prods them too far and they revert to their chav name of ‘stink’bug’. How long before they realise they are the only prey for the bigger enemy – the solitary wasps with a taste for shield bug nymphs on the hunt to stock their nests with the fattest, juiciest specimens to feed their offspring.

 

 

Bright young things

Warwick Gardens was awash with children from Bellenden Primary School last week, running around playing football, shouting and swinging from the swings and generally having a great time. Dolled up in orange high vis vests they virtually dazzled in the sunshine, like little daytime fireflies or mini construction workers having a playtime from mending the rail tracks. But they were not the only bright young things in the park – there were jewel wasps competing for the title of the brightest of bright young things.

Chrysis ignita

Chrysis ignita

If you look closely amongst the shrubs you might see a flash of metallic blue/green and red skittering around on the leaves. These are the ruby-tailed wasp Chrysis ignita. Whenever I see them they are running up and down stems, pausing occasionally to have a sniff using their downward-curving antennae to pick up the scent of their host insect. As a cuckoo wasp they are looking for mason bee nests. Once the female finds the nest she explores the entrance to make sure no one is home then sneaks inside and lays her eggs. With a hard body cuticle to protect from stings she is well-equipped to defend herself if she comes under attack from an angry host bee – she curls up into a ball. The eggs hatch into larvae, which eat the newborn host species. The larva complete their development inside the nest and the adults emerge the following spring.

Hedychrum niemelai

Another jewel wasp to look out for is Hedychrum niemelai. Its the first time I have seen this beautiful shiny wasp in Warwick Gardens. They love to come out in bright sunshine to feast on the yarrow. The female lays her eggs in the nest of the digger wasp Cerceris arenaria – another first sighting for Warwick Gardens. If a host insect is nesting you can be sure to find its cuckoo!
