Virtual Insects' Reality

This website contains some
parts of my master thesis "Dynamik der Gesangsinteraktion
bei der Laubheuschrecke Mecopoda elongata L." ("Dynamics of Calling Song
Interactions in the Katydid Mecopoda elongata L.").
I have done this several years lasting work at the department for zoology
at the University of Graz (Austria),
and was coached by Prof. Heiner Römer.
You can download my programs Kyberniidae and Coupled Oscillators.
Both are free, but I would be pleased to get mail with your comments!
Background and experimental results about calling song of the katydid Mecopoda elongata.
I highly recomment to study this page before downloading and playing with
Kyberniidae and Coupled Oscillators.
This DOS-program simulates and demonstrates in realtime the dynamics of song
interaction between two singing grasshoppers -
or more technical: of two mutually coupled nonlinear oscillators -
based on experimental determined PRCs and the chirp cycle length in freerun of
Based on the idea of cellular automates this DOS-program simulates the spacio-temporal
patterns of choirs consisting of hundreds or thousands of singing grasshoppers.
(By the way the background picture of this page is a little bit
modified screenshot from Coupled Oscillators!)
