AMSTERDAM — Every summer when Dutch people flock to cafe terraces they are joined by legions of annoyingly persistent wasps.

This summer should be different. A heavy freeze in the beginning of March killed off much of the latest generation of wasps, Marijke van Damme of the Royal Dutch Society for Study of Wildlife (KNNV) said on Friday.

"Mild winters lead to a plague of wasps in the early summer. This is not the case this year," she said.

While many wasp-o-phobes may be delighted to hear this, it is not necessarily all good news.

Wasps colonies consume a lot of flies and mosquitoes. A 'shortage' of wasps can therefore translate into far more mosquitoes later in the year. So far this year, there have not been so many mosquitoes but a lot of flies.

But if August warms up — as is predicted by the meteorological bureau KNMI — the larva that are now growing in pools of water on flat roofs will turn into a plague of blood-sucking mosquitoes, Van Damme warned.
