Štys I am not particularly focused on the Pentatomoidea. This superfamily represents for me one of the distinct clades of Heteroptera (although, in my opinion, with still unsufficiently corroborated monophyly), which must be included in any comparative study of true bugs. As such I am concerned with pentatomoids in the following studies: 1) infraorder and family level phylogeny and higher classification of the Heteroptera; 2) architecture, venation and articulation of wings in the Hemiptera (jointly with J. Kukalová-Peck); 3) attitudes of passerine birds towards the red-and-black warning coloured complex of European Heteroptera (jointly with A. Exnerová, J. Zrzavý and others); and 4) antipredatory defenses in Heteroptera (jointly with A. Exnerová).

Current Projects:
1) A new group of pentatomids, the arrow-headed bugs, from Australia and its enigmatic morphology (mainly head, stylet bundle, labium, stridulation mechanisms in larvae [different from that of adults]).
2) A new subfamily of Urostylididae from Madagascar
3) Sexual dimorphism in cephalic morphology of the Pentatomoidea, and its function.
4) Breakup of customary diagnostic characters in some higher pentatomoid taxa from Madagascar.
5) Larval anatomy of Ceratozygum (Cyrtocoridae).
