Identification & Distribution

Adults of Miris striatus (see first picture below) have a cuneus that varies from yellow to orange-red, but is never black tipped (cf. Rhabdomiris striatellus, which has a black-tipped cuneus). The adult body length is 9-11 mm. The nymphs (second picture below) are ant-like with yellow markings and reddish brown legs.

Miris striatus is usually found on oak or hawthorn and overwinters in the egg stage. It is reported to be largely predatory feeding on small insects such as aphids and the eggs and larvae of moths and beetles. It has also been recorded feeding on aphid honeydew (Wheeler, 2001 ).

Acknowledgements

For the mirid bugs we have used Southwood & Leston (1959)  and British Bugs  to aid in identification and for the key characteristics.

For aphids we have made provisional identifications from high resolution photos of living specimens, along with host plant identity. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. We have used the keys and species accounts of Blackman & Eastop (1994)  and Blackman & Eastop (2006)  supplemented with Blackman (1974) , Stroyan (1977) , Stroyan (1984) , Blackman & Eastop (1984) , Heie (1980-1995) , Dixon & Thieme (2007)  and Blackman (2010) . We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure  provided by Blackman & Eastop (2006).
