Locusts in Fuerteventura - Esperanza or Tettigoniidae

The Locusts that live in Fuerteventura, including Esperanza or Tettoniidae. 

Do you find locusts in Fuerteventura? 

Well, the answer is a definite yes, but its not something you see everyday. However, there are occasions when millions of locusts decend on the islands and dessimate crops, but thankfully they are not that common. 

Its currently Feb 2026 and once again swarms of locusts are being spotted across the Canary islands, carried from the African continent by the prevailling winds. 

The last time we saw swarms of this size were back in 2004 and also in the late 80's, but the worst infestation by far was back in 1958 where more than 10,000 hectares of crops were destroyed in a matter of days. Luckly nowadays the local departments of argiculture are armed and ready to act. 

But what are these locusts and what do they look like.

Locusts are a grass hopper which is an insect from the Tettigoniidae family. A large family which includes around 6,400 different species. They are robust creatures and can be found on every continent except Antarctica. They are commonly called ‘Bush crickets,’ ‘Esperanza’s’ or ‘Katydid’s’ and thrive in tropical regions, where the conditions are cool, dry and temperate, such as Northern America.  

What do Locusts in the Canary Islands look like?

Tettigoniids range in size between 5cm and 130cm and although they look like a grasshopper or locust, are actually more of a cricket and distinguished by the length of their antennae which can be as long as their whole body. Locusts antennae are shorter, as you can see in the photo.

What do Canarian Locusts eat?

Tettigoniids are nocturnal, tree-living insects that normally feed on leaves, flowers, bark, and seeds. The amount of nutrition available often dictates the lengths to which they can grow, with smaller species living in more stressful, with poor vegetation. However, that is not always the case, as some of the larger species are predatory and will also feed on other insects, snails and even small vertebrates such as snakes or lizards too. 

What sound do Locusts in Fuerteventura make?

They get the nickname ‘Katydid’ from the sound that they make. The males, and some females, have sound producing organs on their front wings. One side is formed like a comb and has tough ridges, the other is smooth, like a plectrum. When the two are rubbed together, it produces a high pitched trill.  

Are there many locusts in Fuerteventura?

We have had whole plagues of them and anyone that has lived here a while, will remember those experiences vividly.  But do we see them on a regular basis? The answer is no, as they prefer the greener Canary Islands and luckily Fuerteventura is mainly dessert! Phew!
