Abstract
Abstract. 1. Mark–release–recapture studies were conducted on two species of chequerspot butterfly,Euphydryas auriniaandMelitaea phoebe, in the same habitat patch network in Yanjiaping, a small basin in the Taihang Mountains, north‐west of Beijing, China, in 2000.2.Euphydryas auriniatended to stay in the habitat patches and to move to neighbouring patches, whereasM. phoebemoved widely among patches in the entire network.3. The parameters of the virtual migration model showed higher daily emigration propensity inM. phoebeand inE. auriniamales than inE. auriniafemales, and significantly greater average daily movement distance inM. phoebethan inE. aurinia.4. The results are consistent with the previous findings showing genetic structuring among local populations ofE. auriniabut not among local populations ofM. phoebe.5. Based on the genetic and ecological results, it was concluded thatE. auriniahas a classic metapopulation in the study area, whereasM. phoebeappears to have a source–sink metapopulation.6. In 2000, when there was an overall increase in the abundance of the two species, the limited mobility ofE. auriniaresulted in an increase in the average local population size, whereas the increase in the number of local populations inM. phoebewas due to its high mobility.
