3 caterpillars in need of a name .

I have ploughed through Porter's caterpillar book and checked out Ukmoths website but I cannot find an ID for any of these caterpillars.NO 3 looks vaguely like a Winter Moth but not quite .No 2 similar to a small engrailed and No1, I have no idea . Can anybody put me out of my misery please ?All three were seen in deciduous woodland in southern England.

    Number 3, what about a Hebrew Character?

    Could number 1 be a scalloped oak - long shot perhaps,

    Hi Torcross

    Date, foodplant, place and length (measured on mm graph paper - guesses often mislead) would help narrow the search for larval queries.

    My suggestions are

    1. Possibly Scarce umber if found April- June, but I'm very uncertain. The posterior is wrong for Scalloped oak.

    2. Probably Scarce umber if found April-June on one of its foodplants. Not Feathered thorn, as it should have a pair of conical warts (usually orange) on posterior segment. (the orange point in your photo is tip of leaf behind the larva).

    3. If found mid April-mid June I'm pretty sure it is the Dun bar as it has black pinacula (small round warts with setae growing from them) and only a few macro moth larvae have black pinacula. Hebrew character does not have black pinacula. Dun bar eats other larvae, so rear each one separately.

     

    ukleps website has a more complete series of different macro larval instars than ukmoths, though the latter is better for micro larvae. Porter only shows 1 or 2 of the five instars for each sp.

     

    Rearing what you photograph is the surest way to get id.

    Best wishes

    Ian
