Fascinating facts about the Dark-Spotted Palthis Moth
- A moth first named in 1796 still flutters across North America today, showing how long a single species can persist in scientific records. Jacob Hübner's 1796 description anchors modern studies, reminding us that even tiny insects have centuries-long histories worth tracking.
- From Newfoundland west to coastal British Columbia and south to Florida and Texas, the dark-spotted palthis occupies a broad range. This range means the moth adapts to many climates, highlighting the flexibility of its diet that includes alder, birch, fir, oak and dozens of other plants.
- Its wingspan stretches only 20-26 mm, about the width of a standard paperclip, yet the adult flies from May through August in Alberta.
- In the eastern portion of its range the dark-spotted palthis typically produces two generations each year, whereas populations further south, beginning in Missouri, are capable of three or more generations annually. Adult moths are active and on the wing from May through August in Alberta, a period that coincides with the warmer months of the northern part of its range.
- The caterpillars of the dark-spotted palthis are polyphagous, feeding on a wide assortment of plant types that include both herbaceous forbs and woody shrubs or trees. Recorded host plants span alder, birch, fir and spruce among many others such as aster, basswood, chestnut, sweetgale, goldenrod, ninebark, rhododendron and scrub oak.
