On May 3, 2023, we conducted the second field visit as part of the "25 years later" series. Our goal was the same small mixed forest near the flood meadow in Lodz. We have made positive observations, such as intense wild boar activity and the flowering of many species of wildflowers.


Our observations in 1997: Nymphalis polychloros (Large Tortoiseshell) - 3 specimens, Nymphalis io (Peacock) - 8 specimens, Nymphalis urticae (Small Tortoiseshell) - 2 specimens, Araschnia levana (European Map) - 1 specimen, Issoria lathonia (Queen of Spain Fritillary) - 1 specimen, Pararge aegeria (Speckled Wood) - 0 specimens, Gonepteryx rhamni (Brimstone) - 2 specimens, Anthocharis cardamines (Orange Tip) - 0 specimens, Pieris napi (Greenvein White) - 10 specimens, Pieris rapae (Small White) - 2 specimens, Pieris brassicae (Large White) - 2 specimens.

We have not previously recorded Pieris brassicae, Pieris rapae, Nymphalis polychloros, Nymphalis urticae, Araschnia levana and Issoria lathonia. However, we noted the presence of Anthocharis cardamines and Pararge aegeria.

The overall impression is that the number of specimens has increased and the number of species has decreased from 9 to 5.

It is worth noting the change in the number of butterflies, we recorded an increase in the total number of butterflies from 32 to 50.


Railway lines - new way to biodiversity

Used and especially disused railway lines have great potential in recreating the diversity of butterflies and moths.


Chalk, gypsum and limestone grasslands

Gypsum, chalk and limestone grasslands are also extremely valuable habitats. It creates exceptional conditions for many butterflies, moths and other species.
