Brown marmorated stink bug nymph (likely)

Gardens, orchards, woodland edges, and buildings; commonly found on fruit trees and ornamental plants.

Pierces plant tissues and sucks sap from leaves, stems, fruits, and seeds, potentially causing spotting and deformation.

Nymphs pass through five stages and often cluster on host plants. Adults disperse widely and overwinter in sheltered buildings; they release a strong odor when disturbed.

A significant agricultural and garden pest, damaging fruits and vegetables, but it does not bite or sting people. Identification is somewhat uncertain because the image shows a slender, brown insect partly obscured by the plant.
