The reverse graffiti being the work of a UK artist called Moose, one of the people to have pioneered the movement of "Clean Art" where stencils are placed and then a cleaning solution is applied to leave the fairly permanent, but still temporary form of art.
Moose a.k.a Paul Curtis, was one of the team of people behind the Leeds based Soundclash and he also promoted the Soundclash club nights at which Andy Weatherall was an early fixture and Tricky made a rare and reputedly dreadful early DJ appearance.
Moose says of his vision and how he began making clean art of his own "I just saw marks on the wall where the shoulders of unsteady drunks and the fingertips of curious children had exposed the shiny White tile" And with only a pair of socks as his tool, reverse graffiti was born.
Moose has been doing this for over ten years now and has worked on many commissions often highlighting various health and awareness campaigns and St Leonards certainly needs some help there! It's high quantity of dirty walls means it has the higher proportion of Moths over it's Hastings neighbour.
There are currently 7 locations where the moths are living, hopefully those numbers will increase over time and maybe even encourage more forms of art in unloved places. Each site has a different moth design unique in its complexity, all of the designs are also based on moths native specifically to the area.
The project has 100% backing from the council and more specifically councillor Peter Chowney (In charge of regeneration in the area) who has said "It's an exciting installation which has enhanced the Hastings landscape, it's also great fun to suddenly come upon one of these images walking around town"
