And yet another one from Meganisi, this time Pholidoptera fallax (I think)
The only Eupholidoptera recorded hereabouts are leucasi and megastyla*. I can’t see it as either of those. Might it be a Pholidoptera? I’ll try and get a voucher specimen next time I’m there. They are very common – a good half of all the crickets you see.

My only source for information on Greek orthoptera is Willemse (1984). According to him E.chabrieri is present in north-western Greece, but only on the mainland and Corfu. The only Pholidoptera to come anywhere near Meganisi is P.femorata, and I am familiar with that, and have never seen one like your specimen. As you say, the answer is to collect a voucher. Thanks for that reference.
