A pale oval beetle larva with spiny spikes radiating around the sides of the body sits on the underside of a hairy green leaf. It's carrying dark, dried cast skins on its back for protection.

Predators got you down? Want to hide from the world?
Just slough off your skin and flop it on your back! 👍 #lifehack

#Longitarsus_spec is een klein, springend bladhaantje ( #Chrysomelidae ) met verdikte achterpoten. Het leeft op kruiden en grassen, waar het bladeren aanvreet. Veel soorten lijken sterk op elkaar en zijn lastig op naam te brengen zonder microscoop.

Circular hole chewed in a brown seedpod. Nearby is the circular door that was pushed open by the escaping beetle. An extremely small, almost translucent mite is walking toward the hole.

This little cutie-pie, and I do mean little at about 3mm or so, is possibly a Willow Flea Beetle - Crepidodera aurata. If not then it's certainly in that genus 😅 Gorgeous little beets 😍 #insect #insects #macro #macrophotography #olympusem1mk3 #leafbeetle #chrysomelidae

Nahaufnahme eines Sermylassa halensis Blattkäfers auf einem grünen Blatt. Der Käfer zeigt seine charakteristische Färbung mit einem leuchtend türkis-grün schimmernden Halsschild und Flügeldecken sowie einem orange-braunen Kopf und Beinen. Die metallisch glänzende Oberfläche weist eine feine punktierte Struktur auf.

Seitenansicht eines Sermylassa halensis Käfers auf einem Blatt. Deutlich erkennbar sind die großen schwarzen Facettenaugen, der orange gefärbte Kopf und Thorax sowie die irisierenden blau-grünen Flügeldecken mit ihrer charakteristischen punktierten Oberflächenstruktur. Die Beine sind ebenfalls orange-braun gefärbt.

Frontale Aufnahme eines Sermylassa halensis Blattkäfers, die den Kopf und die Mundwerkzeuge deutlich zeigt. Der orange-braune Kopf kontrastiert stark mit den schwarzen Augen und dem metallisch schimmernden türkis-blauen Halsschild. Die Fühler sind gut sichtbar und die Flügeldecken zeigen den typischen Metallglanz.

Dorsale Ansicht eines Sermylassa halensis Käfers von oben, die die ovale Körperform und die Proportionen zwischen Kopf, Thorax und Abdomen zeigt. Die metallisch glänzenden Flügeldecken dominieren das Bild mit ihrer türkis-grünen Färbung und der feinen Punktierung, während Kopf und Beine in warmen Orange-Braun-Tönen gehalten sind.

Den bunten wärmeliebenden Halleschen Blattkäfer (Sermylassa halensis) kann man aktuell an seinen Futterpflanzen (Labkräutern - Galium sp.), an Wald- und Wegrändern finden.

Ein metallisch schimmernder Blattkäfer (Chrysolina fastuosa) sitzt auf einem grünen Blatt. Der Käfer zeigt eine prächtige irisierend grün-golden-kupferfarbene Oberflächenstruktur mit deutlich sichtbaren Punktreihen auf den Flügeldecken. Seine Fühler sind dunkel und perlschnurartig gegliedert. Der kompakte, ovale Körper reflektiert das Licht in verschiedenen Grün- und Goldtönen, während die Beine schwarz gefärbt sind. Das Insekt ist scharf vor einem unscharfen, hellgrünen Hintergrund abgebildet.

Der Prächtige Blattkäfer (Fasta fastuosa) ist oft an Hohlzahn (Galeopsis) zu finden. Nehmt doch beim nächsten Spaziergang eine Lupe mit und schaut euch diesen prächtigen Käfer genauer an.
