Vitus Graber (1844 - 1892) war ein osterreichischer Zoologe. Seinem Spezialgebiet, der Entomologie, tragt er mit einem zweibandigen umfangreichen Werk Rechnung. In dem hier vorliegenden ersten Band legt Graber seinen Fokus auf den Organismus der Insekten, den er prazise und detailgenau erlautert. Im zweiten Band legt Graber seinen Schwerpunkt auf eine vergleichende Lebens- und Entwicklungsgeschichte der Insekten. Sorgfaltig bearbeiteter Nachdruck der Originalausgabe von 1877.
