queen start a colony on her own?","No. A young queen is a temporary social parasite: she enters a nest of another Lasius ant, usually a queenless Lasius umbratus colony, and its workers raise her first brood until her own daughters replace them. Lasius umbratus is itself a parasite of Lasius niger, so Lasius fuliginosus is called a hyperparasite. Keepers have also started queens with Lasius niger workers and cocoons.",{"question":225,"answer":226},"What is the carton nest of Lasius fuliginosus made of?","Mostly chewed wood glued together with saliva and sugary honeydew, shaped into thin, wavy walls inside hollow trees, stumps, fence posts or beams. A fungus called Cladosporium myrmecophilum grows through the carton and strengthens it. The ants do not eat the fungus.",{"question":228,"answer":229},"Why does a Lasius fuliginosus nest smell so strong?","When the nest is disturbed, the workers release scented secretions from their mandibular glands, including dendrolasin. To people it is just a sweetish smell, but to other ants it works as an alarm signal and helps drive off rival ants.","Glossy jet black workers with a big, heart-shaped head that sets them apart from other black Lasius such as Lasius niger, often seen running in dense trails up trees to tend aphids. The queen is also glossy black and barely larger than a big worker, and the nest gives off a sweetish smell.","en",{},true,[235,238,240,243],{"kind":236,"text":237},"tip","Most keepers start with an adopted queen: soon after the flight, put her with a group of young Lasius workers and plenty of cocoons.
