Hi Laura It's a harvestman (Opiliones) - a harmless relative of spiders. Apart from providing food for *Anthrenus*, etc., they will do no harm. They prey upon small invertebrates. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH England mobile: +44(0)7880707834 phone: +44(0)1603 453524

The sticky trap has Sciaridae, aphids and thrips - shouldn't cause any problems as long as the bodies don't pile up. The major issue will be the Christmas pedants pointing out that the picture of the thrip is actually a picture of a thrips! Have a good holiday, everyone! Tony Dr A.G.Irwin 47 The A

The first is a ladybug beetle (Coccinellidae), which appears to have provided lunch for an *Anthrenus *larva, or possibly a pest moth caterpillar. The second is a hoverfly (Syrphidae) in the genus *Sphegina *- another accidental visitor. Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk NR2 3PH Eng

Hi Helene A quick glance suggests this is a microgastrine braconid - a parasitic wasp. If you only have the one, regard it as an accidental visitor. If you keep finding them, they might be parasitizing a pest species in the collections, but might equally well be the result of a mass emergence outsi

Re: [PestList] Re: Very ancient Bug

I would say it's an immature female earwig, so it may be difficult to put a name to it. Superficially it looks like a *Forficula *species, perhaps even the common European* F. auricularia*, but I have no knowledge of the Oriental fauna, so can't suggest what else it might be. Best wishes Tony Dr A

Re: [pestlist] Pest ID Help

Kevin - You can be reassured that this is not a drugstore beetle (*Stegobium*). However it does look like one of the dermestids, which can be just as troublesome. From the photos I can't decide whether it's a *Trogoderma*, *Attagenus *or perhaps *Anthrenocerus*. (Not sure whether the last one has r

Re: [pestlist] Pest ID Help

Hi Megan This looks very like the Four-spotted Yellowneck, *Oegoconia deauratella*, - not a pest species. The larvae are associated with leaf litter or decaying vegetation, and the adults fly to light, which is why this one is in your building. Best wishes Tony Dr A.G.Irwin 47 The Avenues Norwich

This is a booklouse (Psocoptera), and the colour pattern on the abdomen fits *Dorypteryx domestica*, though I could not exclude other species, based on the photo and video footage. You're welcome to send me a specimen for confirmation. Best wishes Tony Dr A.G.Irwin 47 The Avenues Norwich Norfolk

Re: [pestlist] mystery pod

It appears to be a fly puparium. I can't see enough detail to suggest which family, but I doubt that it represents a threat to the model. It has most likely arrived from outside as a maggot (looking for somewhere to pupate). If you have noticed any funny smells in the building, there might be a hi

Re: [pestlist] Bug ID help!

6105 is a click beetle (Elateridae). 6106 and 6107 are ground beetles (Carabidae). None of them is a pest, just accidental visitors from outside. Do avoid the temptation to re-use the traps - there's enough food in one of those beetles to supply a dozen *Anthrenus*, which are much less desirable! T

Re: [pestlist] Beetle identification

Hi Crista You are right to question their identity. Although they are superficially similar to *Anthrenus verbasci* (Varied Carpet Beetle), these are *Anthrenus coloratus* (Asian Carpet Beetle).

It is *Trixagus *(Throscidae) - one of the "False Click Beetles", a wood boring species that is attracted to light. Not a pest species, though it does turn up in museums and galleries occasionally.
