Hello and welcome to more or less on the BBC World Service. I'm Ben Carter.

We're your weekly guide to the numbers in the news and in life.

And we're here to answer those questions that have been bugging you.

Like this one from Loyal Listener, Janet Watson.

At the end of a recent long car journey, my husband, Andy and I

were struck by how few insects the were splattered on the windscreen,

compared with few years ago.

We've all heard the distressing news of a marked decline in the UK's in-set population,

presumably due to a variety of environmental factors.

But I wondered how much of the windscreen death factor was down to the actual decline in insects

and how much was due to their being significantly more cars on the road.

Thanks, Janet, for your email.

For this, we need to talk to our correspondent for all things creepycrawly, Parisha Cadale.

Hi, Ben.

Our loyal listener isn't the only one who has noticed fewer insect splats on their windscreen.

This observation has become known as the windscreen phenomenon

and there is a study in the UK currently underway to show us whether this is the case

and why exactly it might be happening.

I'm Dr Lawrence Ball. I'm the ecological data analyst lead at Kent Wildlife Trust.

Dr Lawrence Ball is currently leading something called the Bugs Matter Project

as a way to measure insect abundance by using data collected from car registration plates across the UK.

The study was originally conducted by the Royal Society for the Protection of Birds or RSPB in 2004
