Every night homes across the coast are inundated with the gangly legged creatures prompting the question – where on earth do they come from?
Some of us swat, some carefully escort the flying creatures back outside and some, well they just stick them down friends' jumpers!
Rather than being squeamish, children at St Nicholas School in Marton are delighted with the arrival of their new friends, enjoying chasing them round their wildlife garden on School Road.
Headteacher Andy Mellor said: "The Year 1 children have certainly found where the daddy long legs live and have been chasing them round the garden and putting them down each others jumpers.
"There was a mist of them in the playground, they seem to be out in their droves.
"There is a noticeable increase in the number we have seen in school and I have seen at home.
"I wonder if this is another sign of global warming? We have had a very hot summer again this year."
Out in the nature garden the children have been hunting the crane flies, their proper name, with huge success.
Little Liam Wilkinson, five, said: "They have big long legs and big wings and fly around everywhere.
"Sometimes I catch them when they come inside my house but I don't squash them, I put them out in the garden because I like them."
Harrison Farrah, five, agreed: "I like them, they tickle. One day, three came into my room at the same time and I caught all of them and put them outside."
But they are not quite so safe at Charity Johnson's house. The five-year-old said: "My mummy doesn't like them so she squashes them when they come in the house."
Entomologist Peter Flint, of Lancaster University, said the unique weather conditions this summer could explain the influx.
He said: "The larvae live underground feeding on plant roots, which benefit from a good deal of sun. When they become pupa, right before they emerge as a fly, they need a little rain to soften the ground to allow them to wriggle out, which are exactly the conditions we've had recently.
"If it had been hot without the rain it might have been too hard for them to get out and they would have stopped feeding and ultimately could have died, and if it was too wet they might come up too early and been eaten by birds.
"They are actually around all year, but in the summer we leave windows open and lights on so more are attracted into our homes and we notice them more."
