Is anyone familiar with this bug?. I'm pretty sure it's of the family Scutelleridae and an Odontotarsus sp. either O. robustus or O. pupureolineatus. Can anyone confirm this and say which one it is. I think both are recorded for Corsica 29.5.2010 Corsica c 10mms at c 500m altitude on Crown daisy. nick upton attached the following image:  [126.73Kb] Edited by nick upton on 30-11-2010 21:23 Nick Upton - naturalist and photographer |

Thanks Jorge. Seems you agree I got the right genus, and maybe your guess is as good as mine re the species. I think it's probably O. purpureolineatus (it certainly has some purple lines/ stripes) but I've seen pics of O. robsustus (allegedly) looking veery similar and as usual I don't have a key to know what really separates them!

Chiave delle specie italiane del genere Odontotarsus Laporte, 1833 1. Scutello che supera di gran lunga l'estremità dell'addome con una appendice spesso rialzata ............................................... Odontotarsus caudatus (Burmeister, 1835) - Scutello senza appendice vistosamente allungata o rialzata............................. 2 2. Le due grandi linee che si trovano sullo scutello in posizione caudale si piegano ad angolo divergendo sensibilmente ................ Odontotarsus robustus Jakovlev, 1883 - Le due grandi linee sullo scutello in posizione caudale sono pressoché diritte e divergono progressivamente........................... Odontotarsus purpureolineatus (Rossi, 1790) I only have this Italian one. Try it! I'd say O. purpureolineatus. Bye, Niels. |

Molto bene. Grazie mille! The distinction seems to rely on how the 2 major lines on the back diverge from the rear end of the extended scutellum. In O. purpureolineatus they should be almost parallel at first and then diverge progressively (As they seem to in my image) , in O. robustus they bend outward more form the start (as in this image http://www.biolib.cz/en/image/id26056/) I already thought O. purpureolineatus looked the closest from the photos i've seen and unless I've translated the key wrong , it suggests that ID is correct. Many thanks again for finding the key. Nick Upton - naturalist and photographer |
