Rhabdomiris striatellus
(Fabricius, 1794)
Striped Oak Bug
Rhabdomiris striatellus is a mirid bug distributed across the Palearctic region, from Europe through Asia Minor to the Caucasus. The is strongly associated with oak trees (Quercus spp.). measure 7–9 mm and display variable coloration from yellow to reddish-brown with distinctive wing patterning. The species exhibits life stage-dependent feeding habits: nymphs feed on plant material while adults are predatory.

Identification
Distinguished from the related Miris striatus by generally smaller size and more consistent striping pattern, though dark morphs can appear similar. The combination of oak association, yellow wing , and dark longitudinal stripes is diagnostic. Examination of male genitalia may be required for definitive separation from similar dark forms of related .

Color Polymorphism
The exhibits notable color variation, with some individuals appearing much darker. This variability has historically contributed to confusion with related species.
Feeding Strategy Shift
The transition from in nymphs to in represents an unusual ontogenetic dietary shift within Miridae.
