ECOLOGICALLY ANNOTATED LIST I. Prairie Invertebrates An exhaustive study of the animal ecology of a region or an as-sociation must be based upon a thorough investigation of the ecolog-ical relations of the individual animals composing it. An ideal an-notated list in an ecological paper should, therefore, include for eachspecies a complete account of its life history, its behavior, its physi-ology, and the structural features which would in any way contributeto an understanding of the response of the animal to its organic andinorganic environment. At present we have no such knowledge ofthe animals of any locality or of any complex association of animals. 159 s. as pOOM ^UlFi<S09(J pooM pe3Q CD Q ?Or C s ?3 5; 13. o t£ O j: r. r;_ u S °i si ^be is o . o. * o p^ «i 160 In a preliminary study, like the present one, it is desirable to recordrather fully the observations made in the region studied, becausewe have so few descriptions of the conditions of life on our effort has been made to give for each species the date of obser-vation or collection, the locality or station where found, observa-tions on habits and life history, and the field numbers of the speci-mens secured. These numbers illustrate how observations may beaccumulated, upon a large number of individuals, without the ob-servers being familiar with them, or even knowing their scientificnames. It is really surprising how little is recorded about some of thecommonest animals of the prairie and forest in zoological animals, particularly those of economic importance, aretreated rather fully, but generally with little relation to their na
