See comments within.Sub-folder: Arthropod micrographs• This sub-folder contains all micrograph imagery files for arthropod specimens collected from pitfall traps.• Micrographs are arranged in the following folder structure:> [Taxonomic Class] (e.g. ‘Insecta’) > [Taxonomic Order] (e.g. ‘Hymenoptera’) > [Taxonomic Family] (if applicable) (e.g. ‘Formicidae’) > [Morphospecies] (e.g. ‘Formicidae MS 1’) > [Micrograph JPEGS] (e.g. ‘ATW_8_2_a_Insecta_Hymenoptera_Formicidae_n=1.jpeg’)• Micrograph file names contain the following information, separated by underscores: ‘[Habitat type]_[Site no.]_[Pitfall trap no.]_[Micrograph no.]_[Class]_[Order]_[Family (if applicable)]_[No. individuals of a given morphospecies in view].jpeg’
