1. An apparatus for identifying arthropods in color-digital image information from a color digital camera system connected to a communications unit, wherein the camera system has a lens, wherein the camera system is configured to obtain a first image of substrate and an arthropod on the substrate and to form first color-digital image information from the first image, wherein the communications unit has an interface operable to communicate across an internet, wherein the communications unit is operatively coupled to the camera system and configured to receive the first color-digital image information from the camera system and to transmit a first signal across the internet, and wherein the first transmitted signal is based on the received first color-digital image information, the apparatus comprising: a computer coupled to the internet that receives the first transmitted signal with the first color-digital image information; a detector, coupled to the computer, that detects the arthropod in the first color-digital image information; a histogram generator, in the computer, that is coupled to receive the first color-digital image information, and to generate a first object-image histogram of the first image based at least in part on the first color-digital image information, wherein the first object-image histogram of the first image has a plurality of bins, each one of the plurality of bins located on: a row corresponding to a value of a first color-space dimension, and a column corresponding to a value of a second color-space dimension; and a classifier, in the computer, that classifies the arthropod based on the first image-object histogram of the first image and provides a categorization identifier based on the classification.
