Keys to Families

There are two kinds of keys offered here: a multiple entry and a dichotomous key.  The multiple entry key allows you to select features of a specimen in any order and, as you select those features, will eliminate any taxa lacking those features from the identification process.  This is particularly useful for identifying damaged specimens in which certain features are missing, and may be of greater use in identifying immatures.  As you enter each feature that your specimen possesses, taxa lacking that feature are eliminated from further consideration, thus narrowing in on a final identification.  The dichotomous key asks you to look at features in a particular order, sequentially narrowing the possible identifications until a final identification is achieved.  You may choose which key to use for identifications by clicking on the appropriate link below:
