A comprehensive source of information on pentatomoid families, especially Pentatomidae; some information is of general interest to heteropterists.
The Host Index has its own entry(1) for convenience of citation.
'The plant bugs of Denmark': a marvelous, bountiful resource covering all the heteropteran fauna, with emphasis on the Miridae. In Danish. Worth exploring in depth... and picking up some language along the way (quite manageable)
