Monarch butterflies’ ancestors migrated
The insects originated in North America, genetics study finds

The earliest monarch butterflies arose in North America and were migratory, contrary to what scientists believed. Over time, the butterflies evolved populations in other locations, some of which stay put year-round, scientists conclude October 1 in Nature.
Because many of the monarch’s closest butterfly relatives live in the tropics and do not migrate, “the thought was that the butterflies [came] from South and Central America and became migratory from resident populations,” says Tyler Flockhart, a conservation biologist who concentrates on monarchs at the University of Guelph in Canada. “But that doesn’t seem to be the case.”
This is a video about a Common Clouded Yellow butterfly.

The next generation of the Common Clouded Yellow, a migratory butterfly, is currently flying again. In places where the species bred in August you can sometimes find ten to fifty butterflies together.
These reports of large numbers of Common Clouded Yellow butterflies come for example from the floodplains of the major rivers and from Zeeland, but the Maasvlakte has the biggest numbers. Here 100 Common Clouded Yellow butterflies can still be seen together on flowery fallow land.
Common Clouded Yellow butterflies come in the spring, in May and June, from the south to our country and reproduce here. The descendants of those immigrants appear in August and these reproduce again. The third generation is now flying, especially places where reproduction went well and where sufficient flowering plants are present are favourites. They will also migrate again and can then be seen everywhere in the country, but large numbers together you will find especially on the breeding sites.

An ichneumon wasp has deposited its eggs in this caterpillar. The larvae then eat their hosts from the inside. These larvae have just crawled out of the caterpillar of a garden white butterfly. Now they are spinning cocoons to transform into wasps. Filmed by Toon Gevers.

The spotted clover is a migratory moth from southern Europe. After thirty years of absence (it was reported in 1958, 1955, 1954, 1953 and 1945) it was observed in Twello (Gelderland) in 1995 and now it has been seen again in Groningen. This is also the most northern discovery of this moth which is not able to survive the Dutch winter.
