The great majority of insect allergic animals just have a simple allergic response – a reaction local to the sting site which appears as just a swelling arising from the release of histamine and other chemicals
Manipulator (insect) Manipulator (insect) Manipulator modificaputis is an extinct predatory cockroach which lived during the Upper Cretaceous period. The holotype specimen is fossilized in a 100-million-year-old piece of amber, which was found in a quarry of volcanoclastic mudstone (a sedimentary rock) at Noije Bum in the Hukawng Valley in Myanmar. The insect has been described by Peter Vršanský, of the Geological Institute SAS of Bratislava, and by Günter Bechly, of the Staatliches Museum für Naturkunde in Stuttgart. The cockroach was found to have an elongated neck, a freely rotating head and unexpectedly long legs, which are indicative of a predatory lifestyle. The
