October in the UK can mean many things – crunchy leaves, chilly air… and the beginning of a ladybird invasion.
Ladybirds begin their season between September and October, finding warm spots in houses to hibernate over the cold months of winter.
2018’s hot summer is likely to have boosted the insect’s numbers, with the Harlequin ladybird, first spotted in the UK in 2004, most likely to be spotted over the autumn weeks.
People have taken to social media to document groups – otherwise known as a “loveliness” – of the insects swarming around their houses, with hilarious commentary.

6. Don’t worry, ladybirds are harmless.
Not sure what happened in the past hour, but suddenly there are like 30 ladybirds on my office window, with a tonne more flying around outside. More ladybirds in one place than I have ever seen before, had to close my window as so many were flying inside the house. Nap time over?

8. Lastly, take a look at this creepy video.
? Have you spotted lots of #ladybirds today? The old Mill building at Woods Mill was covered in harlequin ladybirds this afternoon. Ladybirds tend to gather together at this time of year, looking for cracks and crevices to hibernate overwinter. ? #FridayFeeling pic.twitter.com/FlknTuoWEj
