carl stål -lrb- 1833 -- 1878 -rrb- was a swedish entomologist specialising in hemiptera .
he was born at karlberg castle , stockholm on 21 march 1833 and died at frösundavik near stockholm on 13 june 1878 .
he was the son of architect , author and officer carl stål then colonel , swedish corps of engineers .
he matriculated at uppsala university in 1853 , studying medicine and passing the medico-philosophical examination in 1857 .
he then turned to entomology and completed his ph.d at the university of jena in 1859 .
the same year he became assistant to carl henrik boheman in the zoological department of the swedish museum of natural history in stockholm , where , in 1867 , he was appointed keeper with the title of professor .
he made collecting trips in sweden and throughout europe and visited other museums including the collection of johan christian fabricius in kiel .
his study of the fabrician types resulted in his `` hemiptera fabriciana '' .
a significant part of stål 's work was the study of insects collected from caffraria , the majority of which were poorly understood at the time .
although stål , who was regarded as the world 's foremost worker on hemiptera , published most on this order , he also worked on orthoptera and to a lesser extent on coleoptera and hymenoptera .
in 1869 , he was elected a member of the royal swedish academy of sciences .
