Can you clearly see aphids giving birth to small aphids with a magnifying glass?

Yes, but the magnification requirement is high and the light must be sufficient.

Aphids, also known as grub bugs and honey bugs, are a type of herbivorous insects, including all members of the superfamily Aphididae (also known as Aphidoidea, scientific name: Aphidoidea). There are about 4,400 species of aphids in 10 families that have been discovered so far, most of which belong to the Aphididae family. Aphids are also among the most destructive pests on earth. About 250 of them are serious pests in agriculture, forestry and horticulture.

Aphids vary in size, ranging from one to ten millimeters in length.

The natural enemies of aphids include ladybugs, hoverflies, parasitic wasps, aphid midge larvae, crab spiders, lacewings, and entomopathogenic fungi (including Metarhizium anisopliae).

Aphids are widely distributed around the world, but they are mainly concentrated in temperate regions. Additionally, species diversity is much lower in the tropics than in temperate zones. Aphids can travel long distances, primarily by being carried by the wind; for example, lettuce aphids are thought to have spread from New Zealand to Tasmania this way. Some human activities can also help aphids migrate, such as transporting plants with aphids attached.

The body length is 1.5 to 4.9 mm, most of which are about 2 mm. Sometimes wax powder is used, but wax flakes are missing. The antennae have 6 segments, a few have 5 segments, and rarely have 4 segments. They are circular, rarely oval, and the end of the distal segment is often longer than the base.
