Small Skippers and Essex Skippers
The Small Skipper (Thymelicus sylvestris) and the Essex Skipper (Thymelicus lineola) are two butterfly species which are difficult to distinguish. Only close examination shows a difference in colour of the antennal clubs. Much is still unclear on how the habitats of the two species differ. Although both species are common and occur in more or less similar habitats, the Essex Skipper is more widespread than the Small Skipper in The Netherlands. An appeal is made to gather more information on these skippers.
13.000 caterpillarsAnton Baaijens
Butterfly working groups in the province of Zeeland have been collecting data of butterflies and moths. Two notable observations were the extraordinary large numbers of The Lackey (Malacosoma neustria) in 1999, and the Garden Tiger (Arctia caja) in 2000. The thousands of caterpillars indicated that the species had reached pest proportions. In 2001 the numbers had dropped as a result of parasite infection.
The Garden TigerJan Matheeuwsen
One of the most colourful species of the moth family Actiidae is the Garden Tiger (Arctia caja). In spite of their striking appearance the moths are rarely seen in the daytime because of their sheltered way of living. The male flies at night attracted by the sex pheromones from the female who remains in her hiding-place. The adult Garden Tiger has a short lifespan of only a few days. Caterpillars live longer and are therefore seen more often. The author gives a personal account of rearing a Garden Tiger from caterpillar to adult moth.
The many views of the LötschentalJouke Attenburg
An overview of alpine butterflies of the Lötschental in Switzerland. The Lötschental is a small subsiduary valley of the Rhone valley with three distinct landscapes. These are the open spaces in mountaineous pine forests, wet and dry sub-alpine grassland, and the Walliser steppes. Each landscape has its own flora and fauna including butterflies typical for this habitat. A detailed description of these landscapes with the species of butterfly found here is given.
