Hi Adie Given the distorting effect of the glass, and the probability that these have faded, you've come up with a tough one - it would help to know what size they are. Can you say what size the wire reinforcing mesh is? Thanks Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England

Re: [PestList] Unidentified pests

The psocids in images 1 & 2 have much longer legs than the usual booklice ( *Liposcelis*) - they are likely to be *Dorypteryx*, which is regularly found in Museums, Art Galleries, etc., but does not appear to be as destructive as its cousins. Best wishes Tony Dr A.G.Irwin 47 The Avenues Norwich

Re: [PestList] beetle identification

Alan - I am sure this is not *Anthrenus*, and I don't think it's a dermestid at all. Having said that, I'm not sure which family it is, but it looks very like one of the *Xanthonia *leaf beetles (Chrysomelidae). If it is that then it's an accidental visitor. Tony Dr A.G.Irwin 47 The Avenues

The elytral shape and antennal structure are not right for *Dienerella*. Having said that, I'm not sure what this is - though I know that New Zealand has plenty of strange little beetles that look a bit like this. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England mobile:

Re: [PestList] RE: Moth found in textile storage area

Julie - Oecophoridae includes the Brown House Moth (*Hofmannophila pseudospretella*) and the White-shouldered House Moth (*Endrosis sarcitrella*), both of which can present a danger to stored products, including collections. I don't recognise this species however, so cannot say whether it is an

Re: [PestList] RE: Moth found in textile storage area

Not *Tinea*, which has much smaller palps - this is more like one of the Oecophoridae. Sorry that I'm not familiar with the Nearctic species, so can't suggest a likely suspect. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England mobile: +44(0)7880707834 phone: +44(0)1603 453524 On

Re: [PestList] Moth identification

A noctuid moth - a visitor from outside, so not a direct threat to the collections, but its body provides food for dermestids and other pests, and it would be good to seal wherever it got in. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England mobile: +44(0)7880707834 phone:

Re: [PestList] help with identifying pest

I don't recognise the first beetle, but it's not a pest species as far as I can tell. The second specimen is an oribatid mite (sometimes called beetle mites) - a visitor from outside, rather than a pest. The third picture is of a number of *Dorypteryx *(Psocoptera - booklice). Although regularly

I would agree with Wharf Borer, *Nacerdes melanura*. (Not *Donacia *or Soldier Beetle). It's a species that is usually found in damp (dead) softwoods - either outside, or in structural timbers in damp cellars, etc. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England mobile:

Not Pantry Moth (*Plodia interpunctella*) which has a rather different colouration, but one of the Pygmy Moths (Nepticulidae) - a group of small leaf-mining moths that may come indoors attracted to light, but present no threat to the collections. Identification to species requires dissection, and
