Does anyone know what makes that electric buzzing type noise in the trees?

Everyone we know knows the noise but noone knows what makes it or how they make it.

A pic would be great also.

Thanks.

A lesser spotted chainsaw?

They're Cicada's.

I always thought they made the noise with their legs or wings, but apparently not!

Thanks for that. Ive heard of cicadas but didnt know they made that noise.

They are as ugly as their noise.

They contract and expand their stomaches which act a bit like a drum.

I do that sometimes but it doesn't make that much noise!

bet you do from your



















no - better not

They are quite pretty with their wings like leaded glass windows. I once walked thru a small valley where the olive trees were covered with them, and the noise made the whole place vibrate.

for english people they are called crickets you twats

Crickets they are definitely not.

However Cycada can sometimes be confused with Katydids, one of the differences being that Cycada tend to be noisy during daytime and dusk only, whereas Katydids go on and on, making their noise right through the night.

yes, you're right - & crickets DO make the noise with their legs

There are house crickets, the black field crickets and the burrowing mole crickets, which construct a burrow that acts like an amplifier, and produces an amazing volume of noise. Tracking them down is a hell of a job because the sound appears to come from all around.

The zizzing noise in the trees is deffo the cicadas tho.

Even if they continue throughout the night, which cycadas are not noted for but katydids are ?

Maybe in Spain they are all commonly categorised as cycadas, as we have just seen from our learned sensational friend and his crickets.

Interesting. I've seen cicadas here, grasshoppers, all sizes, and a few crickets other than the house or field, but I don't remember seeing anything like a katydid.
