Microlepidoptera
Microlepidoptera is an artificial (i.e., unranked and not
monophyletic) grouping of
moth and
butterfly families, commonly known as the 'smaller moths' (
Micro,
lepidoptera). In essence, it is any lepidopteran that is not in the
Macrolepidoptera. Efforts have been made to stabilize the validity of the term however have proven inadequate. The vernacular usage of the term microlepidoptera divides the lepidoptera into more-primitive and less-primitive groups using microlepidoptera and macrolepidoptera respectively. Using the term to represent any non
Ditrysia lepidopterans is faulty because there are indeed many large non-ditrysian moths. A good example is the
Hepialidae, or swift moths. These (sometimes impressively large and colorful) moths are considered
basal in the lepidoptera tree of life and are more closely related to many small bodied families of moths. Attempts to use the term scientifically only creates confusion and conveys little information about the taxonomy of the insect. Therefore the only true valid application of the term microlepidoptera is in it's obviously apparent definition.
Microlepidoptera include
*
Tortricidae*
Pyralidae*
Gracillariidae*
Tineidae*
Gelechiidae*
Lecithoceridae*
Limacodidae* and many others.
Microlepidoptera can be found in a broad variety of habitats worldwide. The microlepidoptera are for the most part endophagous (internal) plant feeders that tunnel, or "mine", leaves. Many smaller moths are considered pests or
parasites, causing damage to plants as well as fabrics and other man-made goods. Common varieties include the
plume moth and the
clothes moth or
tineid moth.
