Of our (c) 3,000 moths, many are difficult to see. Not necessarily by being nocturnal but because of their size, choice of habitat or lifestyle. The following species all fall under moth experts' categorisation of 'Micro Moths'. Most of these haven't been given a common name. As it happens a few of the biggest Micro species are bigger than the smallest of the Macro species, but that is just because they are part of a family group of generally small species. Many of this group look very insignificant in the field, if you happen to notice them at all, but close up they are often surprisingly well coloured and patterned.
