Intermountain Leafhopper – Ewardsiana filamenta
Intermountain Leafhopper (Ewardsiana filament)
Common Name: Intermountain Leafhopper
Latin Name: Ewardsiana filamenta
- Leafhoppers, these insects are rather little (3.5-4mm). The wings are kept flat against the pale green body. The tips of the wings become white.
- Leafhoppers are sometimes known as froghoppers because of their frog-like appearance.
- Dults range in color from pale yellow to olive green and are roughly 14 inches long. Because of their color and fast flying, they may be mistaken for whiteflies.
- Nymphs are comparable in size to adults but lack wings and can only be seen on the undersides of leaves.
- The immature stages, sometimes known as nymphs, are smaller and cream-colored. These can be discovered beneath plant leaves.
The rose leafhopper appears to overwinter only on roses (woody plants in the genus Rosa) but can host on other plants during summer. Apple, pear, plum, and cherry are all tree fruit hosts.
Intermountain Leafhoppers are found in Europe, Asia, and North America.
Damages caused by Intermountain Leafhopper:
A widespread and diverse species that feeds (through sucking mouth parts) on the fluids of a range of plants, occasionally harming plants and transferring plant diseases; medically safe, however mature leafhoppers are capable of biting, causing temporary discomfort.
Life history and habits:
Rose leafhopper has three generations yearly, as opposed to the white apple leafhopper, which has two. This species spends the winter as an egg on the stems of roses, causing the same crescent-shaped swelling as the white apple leafhopper. Eggs hatch in early to mid-April, and nymphs remain until early June. The overwintering host confines the first-generation nymphs. This generation’s adults are active from late May to late June. The second and third generations are generated on a rose or a tree fruit host. Adults are active from mid-July to mid-August, with second-generation nymphs appearing in July. Third-generation nymphs are present from late August to September, while adults are present from early September till frost.
