Snout Moths and other “micromoths” of Columbia County, Oregon
Several groups of moths have snout-like appendages, including Hypenine Snout Moths (subfamily Hypeninae), Litter Moths (subfamily Herminiinae), Tortricid Leafroller Moths and Allies (superfamily Tortricoidea), and Pyralid and Crambid Snout Moths (superfamily Pyraloidea). We’ve also included several similarly small moth species here, such as Clothes Moths (superfamily Tineoidea), Ermine Moths (Superfamily Yponomeutoidea), Leaf Miners (superfamily Gracillarioidea), and Curved-horn Moths (superfamily Gelechioidea). A fantastic resource for more specific information on all our moths is Pacific Northwest Moths.
Related to the owlet moths, their name comes from the Greek for “beard”.
Litter Moths (subfamily Herminiinae)
Another member of the Owlet moth family, these feed on the detritus of the forest floor.
Tufted Moths (family Nolidae)
Their caterpillars make a silk cocoon with a vertical exit slit.
Pyralid and Crambid Snout Moths (Pyraloidea)
Pyralid Moths (Pyralidae)
Also known as “Grass Moths”, these tiny moths are considered pests in many areas.
Crambid Snout Moths (Crambidae)
Another family of “Grass Moths”, several are used as biocontrol agents against Water Hyacinth and Eurasian Watermilfoil.
Tortricid Leafroller Moths and Allies (Superfamily Tortricoidea)
These moths get their name from the manner in which host leaves are pulled together as the caterpillars feed on them. Many species are considered orchard or forestry pests.
Ermine Moths and allies (Superfamily Yponomeutoidea)
Small, often brightly colored moths, several of which feed by mining through leaves.
Clothes Moths (superfamily Tineoidea)
This unusual family of moths primarily feeds on nonliving matter, such as fungus, detritus, and feathers. Several have taken to eating clothes, hence the name. Some are also known as “bagworms”, due to the tendency of their larva to encase themselves in a bag-like covering.
Leaf Miners and relatives (superfamily Gracillarioidea)
These moths are named due to the unique manner in which their larva “mine” under the surface of plant matter, rather than eating it from the outside. They are often identified by the tell-tale markings they leave on such leaves.
Curved-horn Moths (superfamily Gelechioidea)
Some larva in this group are called “casebearers” for the manner in which they form a protective covering around their body.
Fairy Longhorn Moths (superfamily Adelidae)
Small diurnal moths that are usually closely associated with their host plant.
