Chrysotachina sp. (French Guiana)

Chrysotachina sp. (French Guiana)
Chrysotachina is a very distinctive genus of metallic coloured tachinids. They are not common but they do come up in samples quite regularly. They have been reared from Hesperidae. Determination by Monty Wood:

Calodexia sp. (Ecuador)

Calodexia sp. (Ecuador)
This Calodexia came from a batch of flies kindly sent to me by Eric Fisher. Monty says that Calodexia are cockroach parasitoids and their oviposition technique may explain the strange down-pointing ovipositor:

Chetogena sp. (French Guiana)

Chetogena sp. (French Guiana)
This is another familiar genus from the Palearctic and North America and these 2 specimens show some extremes of size and morphology – it is quite a diverse genus. Determined by Monty Wood.

Blepharipa sp. (Brazil)

Blepharipa sp. (Brazil)
Blepharipa is a familiar genus of palearctic flies to me, as I am sent them occasionally from European material. But it was quite a surprise to hear Monty say that I had a South American Blepharipa … different species of course (and unknown so far) but the same genus, nonetheless.

Belvosia sp. (including Triacora sp.)

Belvosia sp. (including Triacora sp.)
This is a selection of Belvosia spp. but also including the very closely related Tricora, which is probably a subgenus: Determinations by Monty Wood.

Argyrophylax sp. (Ecuador)

Argyrophylax sp. (Ecuador)
Determination by Monty Wood:

Atacta sp. (French Guiana)

Atacta sp. (French Guiana)
This genus is one of my favourites – related to Belvosia but smaller and brighter in colouration. Determination by Monty Wood:

Archytas (French Guiana & Brazil)

Archytas (French Guiana & Brazil)
The following is a selection of Archytas sp. from both French Guiana and Brazil showing some of the immense diversity of this genus. Despite their huge variability Archytas spp. usually have a characteristic change in colouration between tergites 1-4 and tergite 5 – the whole abdomen is shiny but tergites 1-4 have a faint, pale ...

Anisia sp. (Jamaica)

Anisia sp. (Jamaica)
Many years ago Tony Harman gave me some tachinids that he had reared from a phasimid called Anisomorpha that had been collected from Jamaica. They ‘rested’ in my collection for a number of years until Monty Wood was able to identify them as being Anisia sp. – parasitoids of orthopterans, so the host would be ...

Actinochaeta sp. (Brazil)

Actinochaeta sp. (Brazil)
This lovely little Mintho-type fly was collected in Rondania, Brazil by Eric Fisher and was determined by Monty Wood:

Monty Wood’s neotropical workshop

Monty Wood's neotropical workshop
This weekend has been a real treat for me and I have learned so much. All due to the visit of Monty Wood, who took some time off working at the BMNH to visit me and work on my neotropical material. Monty has been identifying huge numbers of specimens and passing on as much of his ...

Moor Copse – 31st July 2010 1

Moor Copse - 31st July 2010
Funny field-trip today – started badly when I discovered that the Wildlife Trust had put cows into the only field with a decent patch of hogweeds and totally trashed it. Needless destruction of nectar sources really annoys me – they could have put the cows into another field while the hogweeds were flowering but no ...

Warburg Reserve – 18th July 2010 4

Warburg Reserve - 18th July 2010
Today I went for a quick walk around Warburg nature reserve, near Henley-on-Thames. The main idea was to check for Villa cingulata (a rare speciality of the site) and to generally have a look for tachinids. Villa were seen in good numbers around the visitor’s center, The Range and Big Ashes ride – at least ...

Moor Copse – 17th July 2010

Moor Copse - 17th July 2010
The cloud too a long time to clear so I only got out to Moor Copse after 2pm. Still, the insects didn’t seem to matter and the hogweeds were in full flower so it turned out to be a good day. Some highlights are: Nowickia ferox, Phasia hemiptera, Dinera grisescens, and a really amazing Silver-washed ...

Moor Copse – 3rd July 3020 3

Moor Copse - 3rd July 3020
I braved clouds of Cleg flies at Moor Copse today to take some photos and catch some flies. Saw lots of Dinera grisescens and Phasia obesa/pusilla-group and some Exorista rustica-group, a single Nowickia ferox and a superb Stratiomys potamida. One of the nicest sights though were dozens of Silver-washed Fritillaries flying along the river bank ...

A new Estheria sp. 1

A new Estheria sp.
Recently I sent a parcel of difficult tachinids to Peter Tschorsnig and he returned them a few weeks ago, with his identifications. One really interesting result was that a tachinid sent to me by Jorge Almeida (caught Serra da Estrela, Portugal; VII.2009) that I had previously determined as E.picta was actually an example of a ...

Tachinids from the Caucasus and Ural regions

Tachinids from the Caucasus and Ural regions
While on a flying visit to the Moscow University Zoological Museum, Andrey Ozerov kindly let me take a number of their indet. tachinids on loan. The regions covered include the Caucasus, Urals and a few other areas – places which are seldom collected by workers living outside Russia, so it looked like it might yield ...

Moor Copse – 12th June 2010 1

Moor Copse - 12th June 2010
Just a few tachinids today – lots of ragged Zophomyia temula and a few Tachina fera but no sign of any Eurithia yet. One nice highlight though was finding a mating pair of Scarlet Tiger moths on Comfrey. There were also quite a lot of dead Empis tesellata – parasitized by the fungus Entomophaga.

Moor Copse – 25th May 2010

Moor Copse - 25th May 2010
Today the weather has been sunny but not as hot as the previous 3 days so this lunchtime I popped down to Moor Copse to see what was flying. It wasn’t very busy but there were some nice tachinids – notably: a lot of Zophomyia temula flying in and out of the low vegetation; Thelaira ...

Mont Itoupé samples

Mont Itoupé samples
I have just received a really exciting batch of Diptera from Mont Itoupé, French Guiana. This batch comes courtesy of the Parc Amazonien de Guyane and was collected by Stéphane Brule and his colleagues at Société Entomologique Antilles-Guyane (S.E.A.G.). Stéphane also included a few samples that he collected in the northern regions, which come with ...
