\u00a0\u00a0 Jeremy Tatum writes:\u00a0 In this morning’s posting I said how embarrassed I was at having mistaken a caterpillar of a noctuid dagger moth Acronicta impleta <\/em>\u00a0for a species of tussock moth (Orgyia, Dasychira<\/em>) of a quite different Family\u00a0 (Erebidae \u2013 Lymantriinae).\u00a0\u00a0 I am slightly comforted to learn that I am not the first person to be so deceived.\u00a0 In Wagner et al.<\/em>‘s book on noctuid caterpillars, under the description of Acronicta impleta <\/em>I read:\u00a0 The Yellow-haired Dagger provides a promising case for larval mimicry: its caterpillar looks remarkably like those of a tussock moth in the genus Dasychira<\/em>, sharing the same overall shape, lashes and tufts.\u00a0 It matches in detail; e.g., the setae that make up the shorter tufts are densely plumed and downy, like those of a tussock moth caterpillar.\u00a0 Behaviours, too, are copied; when\u00a0 alarmed, the Yellow-haired Dagger caterpillar will arch its first two abdominal segments, more fully displaying its tufts, in much the same fashion as the true tussock moths.\u00a0 As further evidence of the resemblance, let it be known that two of the coauthors of this volume believed they had collected a tussock moth caterpillar at the time the larva was boxed up to Connecticut to be photographed and reared.<\/p>\n

 <\/p>\n

I hope, therefore, that my temporary lapse will be forgiven.<\/p>\n

 <\/p>\n

In any case:\u00a0 If any viewer comes across a tussock caterpillar, please, please retain it.\u00a0 I can give immediate advice on keeping it, or may be able to come and fetch it myself.\u00a0 Quite apart from the possible confusion with the dagger, a new question has arisen, asked both by Sharon Godkin and David Wagner:\u00a0 O.antiqua<\/em> is supposed to have lateral pencils on T3, but these seem to be absent on the caterpillars in this morning’s photographs.\u00a0 \u00a0Also, are we correctly distinguishing between O. antiqua <\/em>\u00a0and O. pseudotsugata<\/em>?<\/p>\n

 <\/p>\n

Bottom line:\u00a0\u00a0 If you find any tussock caterpillars, please retain them and let us know a.s.a.p.\u00a0 We are most<\/span> interested in studying them.<\/p>\n

 <\/p>\n

Well, not quite the bottom line.\u00a0 Just before we go to press I heard from Jeff Gaskin, who writes:<\/p>\n

There were 42 Ringlets <\/strong>at Layritz Park this morning August 19.\u00a0 Plus a further\u00a0 11 Ringlets<\/strong> and 5 Woodland Skippers<\/strong> in the fields on the Horticultural Centre Lands by Markham Road.<\/p>\n

 <\/p>\n

And one more last thing, before I press the Send button.\u00a0 Jochen M\u00f6hr’s Orgyia pseudotsugata <\/em>\u00a0<\/em>(and \u00a0I think there can be no doubt what it is) has just formed a cocoon:<\/p>\n
