stout and curved mandibles... it seems it has no tubercles. Tell me if the abdomen is tappered in its extremity. I agree with Hemerobiidae. I wait for more opinions. |

Thank you for your reaction Jorge, I preciate it. These group of insekts are not easy, so I can learn a lot of it's difficulties  On the inside of the madibles I can see some kind of tubercles, a bit underneath and inside of the mandibles. I give you a magnification of the mouthparts. I don't know what you meant with 'tappered', distributed ?

it was a typo. IT IS "TAPERED" not tappered. Tapered abdomen means: to become gradually narrower or thinner toward one end... |

In Hemerobiidae the body is very slender. In Chrysopidae the body is more stout and it has tubercles and warts in the backs... show me a lateral view of this larva, please. I think I see warts in the back... if so, Chrysopidae. |

i see warts on the backs. if this confirms, so Chrysopidae. If not.. it must be Hemerobiidae.  It would be great if you managed to rear this larva. The imago are much more easy. |

Based on the shape of the antennae I'd say Chrysopidae. The ones we get in our samples at the office have tapering antennae (), whereas those of Hemrobiidae are almost club-like at the tip (not really swollen but certainly not getting narrow in a very gradual way like in the images above). I have never seen that character being used in keys, however.

For what it is worth, the head pattern fits several Hemerobius larvae and none of the other genera as depicted in Killington's 1936/37 Ray Society books. John Bratton |

my initial thought was a coleopteran larvae, carabidae but the lack of cerci seems to rule it out |

Thank you all for your reactions. I'll say it is mostlike Chrysopidae sp., if you do not agree feel free to tell. Robert, |
