A cicada - as Diary readers will surely know - is an insect (found in hot climates making high-pitched, droning sounds) and so it was only appropriate that the RES should turn to Di Burton's Harrogate-based agency for some PR help.
But how did this hire come about? Burton says the RES stumbled upon the aptly-titled agency when hunting out PR support on the internet. The agency's name seems to have captured the RES's imagination.
After presenting to RES boffins, Cicada was hired and account director Andrea McKenzie was given a brief to raise awareness of the RES by illustrating how insects (including cicadae) affect people's everyday lives.
'One in every three mouthfuls of food depends on bee pollenation,' chirps Burton.
And, she adds, insects have relevance to ongoing national stories such as congestion charging and nuclear threats.
'Ken Livingstone can learn about congestion charging by studying ants,' she says, adding: 'If there's a nuclear attack, insects are one of the only things that might survive.'
