Abstract: The effect of early-spring submergence on larvae of a wetland-inhabiting population of the butterfly Neptis rivularis (Scopoli, 1763) (Nymphalidae: Neptini) was investigated in laboratory. Wild-collected, late hibernation larvae originating from inundated marshes of the Trebon Basin (Czech Republic) were exposed to two conditions possibly experienced during the floods, aerated (as under running water) and anoxic (as in still water). Submergence for up to three days did not affect larval survival; longer submergence caused substantial mortality, no larva survived the longest submergence tested (21 days). Since there were no differences between aerated and anoxic treatments, the mortality seemed to be due to a failure of osmotic balance. Very short submergence thus does not influence larval survival in field, but prolonged floods may substantially reduce population size. However, the extent of the floods varies in the years, there are some upland colonies of N. rivularis in the area, and the butterfly is a relatively good disperser. It is thus assumed that the species compensates for inundation-caused mortality by a re-colonisation of its sites.

Abstract: The main British population of Gortyna borelii occurs on the north Essex coast, on sites very close to sea level. During 1999, 2000 and 2001, ovipositing strategies of G. borelii were studied providing details of egg laying behaviour, preferred oviposition host plants, height of ova deposition and distance of the oviposition site from the nearest larval food plant (Peucedanum officinale). Six oviposition host plants were identified, five of which were grass species: 75% of the observations were on Elytrigia atherica and Elytrigia repens with the female depositing eggs between the grass inflorescence and the outer leaf sheath. Sites with the highest incidence of oviposting females were dominated by long, coarse grasses (>75% of ground cover mainly Elytrigia spp.) and a sparse distribution (<25% of ground cover) of Peucedanum officinale. Surface morphology, size and shape of ova were described using scanning electron microscopy. The results of the study are important in the conservation of the species in the United Kingdom.

Title: A long-term comparison of laying date and clutch size in the Red-Backed Shrike (Lanius collurio) in Silesia, Southern Poland

Author: P. Tryjanowski

Author's address: Department of Avian Biology and Ecology, Adam Mickiewicz University, Fredry 10, PL-61-701 Poznan, Poland, e-mail:

Abstract: In this paper laying date and clutch size of breeding Red-backed Shrike Lanius collurio in two time periods (1905–1925 and 1985–1999) in southern Poland are compared. Comparisons were made on two separate data sets: a museum collection and nest-cards from the Polish Nest Record Scheme. No significant differences between time of laying (median was 26 May in both periods) and clutch size (5.01 vs. 5.06, respectively) were found. The possibility of using museum collections and nest-cards to analyse long-term trends in life-history traits is discussed.
