The pollination ecology of Symplocarpus foetidus (L.) W. Salisbury was studied in a seasonally forested flooded bog Québec (Canada) 2008 and 2009. protogynous anthesis duration ranged from 15 to 20 days with, chronologically, female phase about 5 days, bisexual 2 male 9 days. spadix temperature differences with ambient air were higher during the (mean: 13.6°C) than phases 4.5°C). inside floral ...

BACKGROUND Fungus gnats (Sciaroidea) are a globally species rich group of lower Diptera. In Europe, Fennoscandian peninsula in particular holds a notable diversity, ca. 1000 species, of which 10 % are still unnamed. Fungus gnats are predominantly terrestrial insects, but some species dwell in wetland habitats. NEW INFORMATION Eight new fungus gnat species, belonging to the families Keroplatid...

Orfelia fultoni is the only bioluminescent dipteran (Mycetophilidae) found in North America. Its larvae live on stream banks in the Appalachian Mountains. Like their Australasian relative Arachnocampa spp., they build sticky webs to which their bioluminescence attracts flying prey. They bear two translucent lanterns at the extremities of the body, histologically distinct from the single caudal ...

Rewardless orchids attract pollinators by food, sexual, and brood-site mimicry, but other forms of sensory deception may also operate. Helmet orchids (Corybas, Nematoceras and related genera) are often assumed to be brood-site deceivers that mimic the colours and scents of mushrooms to fool female fungus gnats (Mycetophilidae) into attempting oviposition and pollinating flowers. We sampled spec...
