Allolobophora rosea (Savigny) was found to be common in mull type soils beneath bramble (Rubus fruticosus L.). Burrow construction in this soil type in the laboratory at 4.4, 10.0 and 14.8°C ranged between 133 and 516 mm g fresh wt of worm day. Burrowing was affected by both body size and temperature. Rates of soil displacement during burrowing were estimated from burrowing rates, burrow dimensions and soil density; depending on body size and temperature they were in the range 809-1,928 mg dry wt of soil g fresh wt of worm day. These values were in reasonable agreement with measured egestion rates (range: 1,000-2,000 mg dry wt of egesta g fresh wt of worm day). It was concluded that A. rosea eats its way through the soil and is adapted to its rapid turnover. Gut turnover times were calculated to be between 1 and 2.5 h.Direct observation indicated that feeding was by a "grazing" procedure and it was shown that A. rosea preferentially selects the more organic fractions of the soil for ingestion.The evaluation of energy budgets for individual small immature, large immature and adult worms at 10°C revealed respiration to production ratios (R/P) of 1.0, 1.8 and 4.1, respectively. Assimilation efficiencies (A/C) were always less than 2.5%.
玫瑰异唇蚓（萨维尼）在荆棘（欧洲黑莓）下的腐殖质类型土壤中很常见。在实验室中，这种土壤类型在4.4、10.0和14.8°C条件下的洞穴构建量在每克鲜重蚯蚓每天133至516毫米之间。洞穴挖掘受到体型和温度的影响。根据挖掘速率、洞穴尺寸和土壤密度估算挖掘过程中的土壤位移速率；根据体型和温度，其范围为每克鲜重蚯蚓每天809 - 1928毫克干重土壤。这些值与测得的排遗速率（范围：每克鲜重蚯蚓每天1000 - 2000毫克干重排遗物）相当一致。得出的结论是，玫瑰异唇蚓在土壤中穿行觅食，并适应了土壤的快速周转。肠道周转时间经计算在1至2.5小时之间。直接观察表明，其进食方式为“啃食”，并且发现玫瑰异唇蚓优先选择土壤中有机成分更多的部分进行摄取。对10°C条件下的个体小幼蚓、大幼蚓和成年蚯蚓的能量预算评估显示，呼吸与生产比率（R/P）分别为1.0、1.8和4.1。同化效率（A/C）始终低于2.5%。
