July 2024
Single logs from this month:
Once again, weather conditions were mixed with overall higher humidity and more rainfall towards the end of the month. Additionally, I still was dealing with a kidney stone until the 17th, which largely prevented me from conducting proper field trips. Because of this, I divided my main route into two halves and visited each half on different days.
Species that already were seen in June and returned:
- Araschnia levana
- Coenonympha pamphilus
- Cupido minimus
- Issoria lathonia
- Maniola jurtina
- Melanargia galathea
- Ochlodes sylvanus
- Pieris napi
- Pieris rapae
- Polyommatus icarus
- Thymelicus acteon
- Thymelicus lineola
- Thymelicus sylvestris
- Vanessa atalanta
---
- Calopteryx splendens
- Coenagrion mercuriale
Species that were last seen in May and returned:
- Aglais io
- Celastrina argiolus
- Erynnis tages
Species that were last seen in April and returned:
- Papilio machaon
- Pieris brassicae
Species making their first appearances:
- Argynnis paphia
- Cupido argiades
- Lasiommata megera
- Lycanea phlaeas
- Polyommatus coridon
---
- Aeshna cyanea
- Sympetrum sanguineum
M. galathea, T. acteon, I. lathonia, C. argiolus and M. jurtina were seen expanding their territories, whereas E. tages kicked off its its very first second generation in my study area.
So far a single observation, C. argiades was a surprising discovery and was hard to identify due to its damaged wings. It doesn't appear to be native to this particular region, yet.
And although P. coridon is doing fairly well, P. bellargus now appears to be struggling. L. phlaeas, which only was observed at the largel-inaccessible southern parts of the Meisel, was low in numbers, yet a stable occurence.
Hundreds of caterpillars of A. io were discovered on the 30th, indicating that August may become a stronger month than July.
