A Review of Taxonomy

• All organisms are broken into a series of groups, called taxa.– The smallest taxon is the species and the largest

taxon is the domain.

Diptera

• True Flies– 1 pair of membranous wings.– 2nd pair of reduced wings for balancers.– Sucking mouth parts.

Ephemeroptera

• Mayflies– 2 pairs of membranous triangular shaped wings.

Review of Dichotomous Keys

• A dichotemous key is a guide for identification based on a series of steps with “yes” or “no” answers.– The answer at each step guides the user to the

next appropriate step.
