biology
Macrohabitat: Midlands, 664 meters altitude, in rainforest. Microhabitat: Arboreal, on twigs and leaves above the ground. Dispersal abilities: Brachypterous, hence flightless thus vagility limited to walking or running. Seasonal occurrence: Adults have been found in September. Behavior: Arboreal: both canopy and understory of rainforests and tropical moist forests of the Mata Atlantica; some altitude records associated with the Andes and Central America indicate they also occur in cloud forests. These long-legged beetles, many of which are ant-shaped and brachypterous, are found on twigs and foliage in the canopy and understory of moist tropical forests, rain forests, and likely cloud forests; also adults have been found in fogging samples of the tall river-side grass, Gynerium sagittatum (Aubl.) Beauv and stands of the bamboo, Guadua weberbaueri Pilger. Larvae use holes in rotting twigs and perhaps bamboo culms much as other tiger beetle larvae use holes in the ground. Some species make their burrows in the end of broken twigs, others in the lateral surfaces of the twig. The burrows are enlarged as the larva grows. Both adults and larvae are predatory on insects. Although Zikan (1929) reported observations on the way of life of some species in South America, particularly Brazil, the genus remains inadequately known. Naviaux (1998) noted that adults of some species seem to mimic cerambycid beetles; perhaps it is the other way round since all carabids possess well-developed chemical defense systems (pygidial glands and deliverables). (Erwin, 2001; Cassola, 2001; Erwin, 1991; Naviaux, 1998 & 2002; Pearson et al., 1999a, Pearson et al., 1999b, Zikan, 1929)
biology
Macrohabitat: Lowlands to midlands, sea level- 900 meters altitude. In Europe, this species is a pronounced forest beetle except in the humid climate of the west where it occurs in open country. Microhabitat: Clearings, roadsides, vacant lots, open grassy cultivated fields, and forest edges. Adults occur on shaded or open ground that is consisting of moderately dry gravelly, sandy, or loamy ground covered with sparse vegetation, or leaf litter. DIspersal abilities: Wing-polymorphic. European records indicate macropterous adults fly. Seasonal occurrence: Adults have been found in May-November; teneral adults in June-September. Behavior: Adults are mostly diurnal, taking cover on cloudy days under dead leaves or stones, among conifer needles or pieces of wood; they are carnivorous and in Europe, adults have been observed eating Collembola, mites, flies, and other arthropods. Larvae are known to climb on tree trunks. This species is favored by human activities and is an effective colonist. Adults hibernate.
