and parasites.For the first few weeks they must forage alone, feeding the first batch of grubs through to maturity. If the queen dies, eaten by a bird, caught by mould, or trodden underfoot as she struggles to get airborne one cool March morning, the colony

was the result of leatherjackets or chafer grubs, which are so abundant and damaging at this time of year. But on closer inspection I noticed that just about every single blade of affected grass was a golden yellow-orange colour and covered with a dense mass

at the weekend, it was plain to see that the local slugs were showing no signs of slowing down. I uncovered several large clumps of their eggs; clear or slightly off-white spheres, each about 1-2mm in diameter (pictured, above). I gathered the eggs up in a pot

starlings feeding on the lawn, not from any food I'd scattered, but simply pecking away searching for worms and grubs. And a blackbird whose youngster fledged from a nest in my ivy this week has also found the lawn a useful source of food.The drought during
