A new arrival from Peru!

Feb

2010

Today I received a very exciting parcel of peruvian tachinids from John Smit and Menno Reemer. The samples were taken during the last half of 2009 in the Sachavacayoc Centre, Tambopata river region. This is a very species-rich part of the world with a very interesting fauna to me. I will probably take another few ...

Back to the NHM again …

Jan

2010

Recently I had a few chances to go back to the NHM in London and work with the world Diptera collections – it was marvellous! I took along some of my larger & more spectacular specimens from North & South America and tried to identify them (with varying levels of success!). I also took lots of ...

Cholomyia inaequipes (fg-taxon #46) 1

Apr

2009

This is a crazy-looking dexiine tachinid. This subfamily usually have quite elongate legs but this taxon takes it to extremes with hind legs that are actually twice as long as the rest of the body. The photo doesn’t show this very well but I decided to fold the legs up to protect them on this ...

Thelyconychia solivaga January 23, 2015
Recently I have been working on adding a new species to the British list to our key. Thelyconychia solivaga is a small tachinid that seems to live on fairly stony/rocky coastal sites and is very rare in the UK – in fact only 3 specimens have been found so far (by Laurence Clemons in Kent […]
The problem with Phryxe … January 20, 2015
The genus Phryxe contains a few common species (nemea, vulgaris & heraclei) and a few very rare ones (magnicornis & erythrostoma). The key pulls out nemea first by the wide gap between the facial-ridge bristles and the descending parafrontals – wider than the width of antenna-3 plus the mustardy/yellow frontal area. Splitting off heraclei has […]
Gonia face colour January 20, 2015
In the keys to Gonia one of the couplets asks you to consider the shininess of the face but this can be a confusing thing to judge when you only have one specimen. In this mini article I have taken photos of the 2 choices to make it clear. The first thing to do is […]
Linnaemya picta, tessellans & rossica confusion features November 27, 2014
For many years Linnaemya picta had been confused with rossica because early workers (e.g. Fonseca) hadn’t tried using the European keys. Since the ‘discovery’ of picta in Kent it has spread across southern England as far as Bedfordshire, Oxfordshire & Berkshire and so now we have another fairly common black-legged species to confuse with tessellans. […]
Siphona urbana or geniculata? September 9, 2013
In Andersen’s 1996 book “The Siphonini (Diptera: Tachinidae) or Europe” he made several changes to the names of Siphona spp., which have proved a bit confusing. The changes (and subsequent reversions) illustrate a few nice aspects of modern taxonomy and so I thought I would write a little piece on what happened. Every species is […]
