Homoptera 2

Aphid.jpeg

Family: Aphididae


Distinguishing morphological features:

▪ Length: 4-8 mm

▪ Body: Soft-bodied, pear-shaped, green/tan color

▪ Antennae: Thread-like, long (may be as long as body)

▪ Wingless (in this case)

▪ Bilateral posterior dorsal cornicles


Ecological importance: Many aphids produce a sugary secretion called honeydew, and this secretion provides sugar for many other insects.

Economic importance: These animals can be a particular nuisance for plants, especially those in gardens and landscapes, as they suck fluids and nutrients from leaves and flowers. For this reason, these animals are nicknamed "plant lice".

Coleoptera 3

Emerald beetle.jpeg

Common name: Emerald Ash Borer

Scientific name: Agrilus planipennis

Family: Buprestidae


Distinguishing morphological features:

▪ Length: About 8.5 mm

▪ Body: Hard-bodied, elongate, slender

▪ Elytra coloration: Metallic emerald

▪ Antennae: Serrate or nearly thread-like, short


Ecological importance: In their native land of northeast Asia, these beetles do not have a significant impact on native tree populations as their population densities remain low. However, these animals have invaded many parts of the Eastern US and reside in native ash trees. Ash trees provide thermal cover, protection, and seeds for a variety of wildlife, so considerable decreases in this tree population would have far-reaching ecological consequences.

Economic importance: As an invasive species whose larvae bore through trees, these beetles threaten lumber production and trees in suburban landscapes.
