Aphid Under the Microscope
Aphid (Whole Mount), Aphis sp.
This is a whole aphid, a tiny sap-sucking insect, mounted flat on a slide. Classes look at aphids to see a soft-bodied insect with mouthparts built for piercing plants and drinking sap.
This is a whole mount of an aphid (Aphis), a small insect that feeds on plant sap. The body is soft and rounded, with a clear, amber outer covering. The dark area inside is the gut and other organs showing through. Thin, jointed legs stick out from the sides of the body. Aphids pierce plant stems with a slender beak and suck out sap, which makes them common garden pests.
What to look for
- Pear-shaped body: A soft, rounded body that is wider toward the rear.
- Piercing-sucking mouthparts: A slender beak under the head used to pierce plant stems and leaves.
- Antennae: Long, thin, jointed antennae extending forward from the head.
- Legs: Six thin jointed legs attached to the thorax.
- Cornicles: In many aphids, a pair of short tubes stick out from the back of the abdomen.
Questions and answers
What does an aphid look like under a microscope?
An aphid has a soft, pear-shaped body, six thin legs, long antennae, and a slender beak for sucking plant sap. Many aphids also have two small tubes, called cornicles, pointing backward from the abdomen.
Why are aphids studied in biology class?
Aphids are common garden pests that feed on plant sap, so they connect insect anatomy to real ecology and agriculture. Their piercing-sucking mouthparts are a clear example of how mouthparts match an insect's diet.

Viewing this slide in class
This is a scan of a real prepared slide, not a simulation or a drawing. On StudyScope you can pan from the whole slide down to individual structures, always in focus, and measure them in real micrometers with the calibrated ruler. Present it live and every student screen follows your view and annotations. Students join with a room code on Chromebooks, iPads, or any browser, with no accounts.
