9-11.V.2012, Zemplén-Mountains

Two days in the Zemplén Mountains, with my friend Attila Kotán and our museologist colleague, Gábor Hegyessy, from the Kazinczy Museum, Sátoraljaújhely. We visited the places, which I have already seen last year, but several different and for the Zemplén Mountains new species were found. Forty-two species of Elateridae were caught during our trip.

We arrived to the castle park of Füzérradvány in the late afternoon, and started collecting from the old oaks with our long nets. Later at night we were walking from tree to tree, using torches to find saproxylics.

The castle of Füzérradvány. Ancient trees stand here, and lush green clearings divide this old park. Only a small part of the park is frequented, other parts are totally undisturbed, providing ideal habitats for insects.

The last hour before sunset, is the best time for netting the canopy of old trees. Hundreds of insects swarmed around.

Calambus bipustulatus (Linnaeus, 1767) from the net.

Later we walked around these old, dying trees, searching for rare species

This giant plane gave us really good click beetles last year. This time we found the larvae of Limoniscus violaceus (P.W.J. Müller, 1821), the violet click beetle and Elater ferrugineus Linnaeus, 1758.

Rare false darkling beetles, like Melandrya barbata (Fabricius, 1787) were crawling on the wall of the cavity.

Reitterelater bouyoni (Chassain, 1992) was hiding in a small crevice. One of our rarest saproxylic click beetles, develops in hollow trees-

After a quick breakfast we started collecting again.

Attila examined an old lime, and found Oplosia cinerea (Mulsant, 1839) just before emergence.

Later we jumped into our car, and travelled to the Ósva-valley at Telkibánya.

We climbed to the sunny hillside, to this very special biotope.

Our smallest click beetle, Quasimus minutissimus (Germar, 1823) was swarming on vegetation.

On a small clearing several beetles were seen flying in the air, so we prepared our long nets. (photo : G. Hegyessy)

Ctenicera virens (Schrank, 1781) is one of our most amazing click beetles. It is only known from the higher regions of Hungary: the Bükk, Kőszeg, Sopron and Mátra Mountains, and we have two old specimens with the label "Budapest, Jánoshegy". These are the first specimens for the Zemplén Mountains. The males are slimmer, and have distinctively pectinate antennae, while females are a bit larger, up to two centimeters. The best way of catching them was hand-capturing. It was cool to see these colorful beetles flying slowly in the sunhine.

Small yellow flowers attracted jewel beetles from the forest. A quite rare species, Acmaeodera degener (Scopoli, 1763) was caught here.

Longhorns associated with conifers: Tetropium castaneum (Linnaeus, 1758) 

and Tetropium fuscum (Fabricius, 1787).

Our road led to this mountain hayfield, where several large and shiny click beetles were seen flying around.

Actenicerus siaelandicus (O.F. Müller, 1764) prefers wet places in the mountain zone.

pectinicornis (Linnaeus, 1758) male, searching for females.

Our next stop at an old wood pasture.

Anthaxia salicis
(Fabricius, 1777), common on yellow flowers.

On our way home we stopped at the river Bodrog.

Lamia textor
(Linnaeus, 1758) was walking on the ground.

The last click beetle of our trip:
Synaptus filiformis (Fabricius, 1781).
