It's really interesting actually. Everyone was asked why are moths attracted to light?

And we actually don't know for sure. Like lots of scientists have tried to study and have different theories about is it that they use the moon to navigate.

That was a big one. But we actually haven't been able to definitively kind of prove why moths are attracted to light.

So it remains a mystery, one we're still trying to understand.

But while we may not yet know why moths are drawn to light, we do know this.

They are essential.

Often overlooked, moths play a vital role in the balance of our garden ecosystems.

And yet, many species are now under threat.

That's why Wildabout Gardens, the collaboration between the RHS and the Wildlife Trusts

has chosen these winged wonders, as its focus this year, shining a light on their importance

before more of them fade from view.

RHS principal entomologist Dr Haley Jones returns to guide us through the first

and perhaps the most misunderstood stage of a moth's life, the caterpillar.

The mini-gardners, that word alone is enough to trigger alarm. But without

caterpillars, the garden begins to unravel. They're the foundation of so many food chains

supporting the birdsong at dawn and the flicker of bats at dusk. Remove them, and these familiar

sounds and sights begin to disappear. Speaking of birds, the RSPB's Executive Director Emma Marsh joins us to unpack the results

of this year's Big Garden Bird Watch, offering a revealing snapshot of the health of some

of our most cherished garden visitors.

New research suggests that the way we feed birds may be unintentionally contributing to the spread of a disease linked to long-term declines in finch populations.

Emma explains what this means and what gardeners can do to help protect the birds we love.

And finally, we turn to a seasonal highlight, crab apples.
