Thrips (specifically a species common in gardens/greenhouses)

Widely distributed on plants, flowers, leaves, and inside structures like greenhouses and homes.

Mostly herbivorous, feeding on plant sap by piercing cells and sucking out the contents. Some species are predatory.

Thrips often congregate in flowers or on the undersides of leaves. They are capable of sudden, jerky movements and can fly or be carried long distances by wind.

Generally harmless to humans but can cause minor skin irritation or 'bites' when exploring. Primarily considered agricultural pests as they damage crops and ornamentals, and can transmit plant viruses. However, predatory thrips can be beneficial for biological pest control.
