Unfortunately, discolor females in my collection are between 17-25 mm. Large Cryptocheilus alternatus or rubellus my reach 30 mm.
Sorry, but true measurment often is disenchanting :@:@
In a German forum, we had a long discussion about size of Vespa crabro length (the Hornet). Amateurs saw queens with 50 mm or more, but specimens in collections or in scientific literature are not longer than 35 mm (30 mm avarage). The conclusion was that both are right, but amateurs has to proof these large hornet queens by photos. Now, we are waiting for the fotos. B)
