The common long-eared hedgehog has a typical lifespan of from 2 to 7 years, with a maximum recorded lifespan of 7 years and 7 months, and a theoretical lifespan ranging from 3 years and 10 months to 7 years and 7 months; the species reaches sexual maturity from 5 months and 1 week to 9 months. The embryo develops inside the mother, and the young are born pink and blind, receiving nourishment from their mother's milk while their spines appear several hours after birth; this infant stage lasts from 1 month to 1 month and 3 weeks. Following this, the adult stage begins, lasting from 1 year and 11 months to 5 years and 6 months, during which the individual forages for food independently and is capable of reproduction.
