I have observed this Eared Leafhopper in my garden close to a Cherry tree and a Hazelnut tree, unless it came from the nearby forest where many Oaks grow. |

I have moved this Eared Leafhopper onto a white sheet of paper and as it stayed perfectly immobile I have tried some "photo stacking". This image is a merge of the sharp areas of 6 photos, each one shot after a small move of the camera. The goal is to increase the depth of field. |

Here is the Eared Leafhopper's larva, observed in my garden where there are no Oaks. It is very flattened in shape and can be difficult to see on tree bark. I had some luck here with a uniform surface. |

I took a few shots and not completely satisfied with the results, I came back a few minutes later and the larva had disappeared. I am very curious to know how and at what speed it moves, hoping to be able to observe this movement in the future... |
