2/5 #WBTC1 #EvoBeh1 We found out that R. nitidula is very common, 
sing exposed to bat predation and don’t stop
when around. We also fed with alive
, however wild bats don’t eat R. nitidula (
25 M.myotis and 25 M.blythii 
metabarcoding
samples)

3/5 #WBTC1 #EvoBeh1 We then trained M. myotis to catch tethered mealworms 1 m in front of 
array mimicking a chorus of singing . We used custom made affordable 
3D setup to record bat predation success and recreate flight velocity and the direction of the attack.

4/5 #WBTC1 #EvoBeh1 Our preliminary results (2 out of 8 analyzed) show a significant reduction of the bats’ predation success in the presence of R. nitidula song (X2 =7.6421, df =1, p < 0.006) compared to the silence control.
