They’re found on broadleaf trees, including elm, aspen, hawthorn, and poplar as well as shrubs and bushes. Leafminers are a major cause of poor harvest numbers in home gardens as they weaken individual vegetable plants.]]> 2019-04-10 15:09:41 UTC https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395780 kiele_short https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395781 Females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Once the crawler selects a feeding site, it inserts its mouthpart  and begins feeding on plant sap. While eating, a sticky waste substance is excreted by the insect. ]]> 2019-04-10 15:09:41 UTC https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395781 kiele_short https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395782 The scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. They comprise the superfamily Coccoidea, previously placed in the now obsolete group called "Homoptera". There are about 8,000 described species of scale insects. Scale insects feed by sucking sap from trees and shrubs through piercing-sucking mouth parts. Sap feeding by scale insects may cause yellowing or wilting of leaves, stunting or unthrifty appearance of the plants, and eventually death of all or part of the plant when infestations are heavy.]]> 2019-04-10 15:09:41 UTC https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395782 kiele_short https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395783 Caterpillars are the larvae of butterflies and moths. They can be serious garden pests, depending on the species. They can be smooth or fuzzy, dull or bright.

-Damage plants by chewing on leaves]]> 2019-04-10 15:09:41 UTC https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395783 kiele_short https://padlet.com/kiele_short/kadu9vj4o5us/wish/350395784 Young nymphs overwinter on the leaves of host plants. In late spring adult females deposit 200-400 eggs in circular clusters on the undersides of upper leaves. The eggs hatch in 5-10 days and first instar nymphs.  They can reduce yield directly through their feeding on leaf tissue, which removes plant sap and stunts plant growth.
