Pos Malaysia released a set of mint stamps and a miniature sheet on May 10, 2010. These stamps and miniature sheet depict fireflies. A total of four firefly species were depicted on the stamps and the miniature sheet - Pteroptyx valida, Pteroptyx bearni, Diaphanes sp. and Lychnuris sp. I am personally not in favour of the stamp design because the background colour of the stamps is too dark, and this is definitely not too good for postage use to get clear postmark cancellation on the stamps. I always like white background design when come to stamps depicting living organisms (plants, flowers, insects, birds etc.).
