Differently, in our paper, SLO attempts to simulate the foraging behavior of a seven-spot ladybird which is rarely researched in the field of metaheuristic algorithm.

In the UK, of the eight species examined, only the seven-spot ladybird, a large insect which is not in as much direct competition for habitat with the harlequin as other species, had not experienced falling numbers.

They are the first sightings of seven-spot ladybirds, frogspawn, red-tailed bumblebees, peacock butterflies, flowering hawthorn and swifts.

In itself that was a somewhat incredible effort, being only seven-spots off Droopys Shearer's track record, and merits a rating of 117.
