Nature ranger Frans Kapteijns identified several species in response to readers’ observations. A sea onion found near Jávea in Spain was described as a large, toxic bulbous plant with tall white flower clusters. A large butterfly was identified as a wind-tailed hawk-moth, which can migrate from southern Europe and Africa and reach short-term speeds of up to 100 kilometres per hour. Other identifications included a Nile goose, a straight coral fungus and a lower fungus that helps decompose other fungi and organic material.

The following week, Kapteijns identified a male mandarin duck near Vlijmen and Haarsteeg, a cross spider guarding a cocoon containing an estimated 300 to 800 eggs, and a young leaf-wasp larva found on a rose plant. The exact leaf-wasp species could not be determined. A squid fungus, originally from Australia and New Zealand, was also featured. Nature activities were announced in the Loonse and Drunense Duinen and the Maashorst nature reserve in November.
