The small agelenid Tuberta maerens (O. P.-Cambridge) is remarkable for its long lifespan (up to four years in captivity), small number of moults after leaving the egg sac (three) and small clutch size (three). It appears to be local because it is highly specialised to certain substrates and (warm) microclimatic regimes, particularly on tree trunks, and is slow to disperse. Psocoptera are probably important in the diet, and an ichneumonid wasp, Gnypetomorpha sp., is a significant egg parasitoid in at least one site. none
