Pseudosiphona sp. (Surinam)

Oct

2010

Pseudosiphona is a very common genus in the neotropics – in these photos you can see the small labellum (much shorter than in Siphona) and the katepisternal bristle arrangement (with the strong lower bristle close to the posteroventral edge) typical of this genus.

Copecrypta sp. (Surinam)

Oct

2010

This is the first of a batch of flies sent to me by Menno Reemer and caught by him in Surinam in 2006. Copecrypta (and the allied genera Deopalpus & Itacuphocera) are some of my favourites. They all have an interesting ant- or beetle-shaped abdomen.

Pseudosiphona sp. (French Guiana)

Oct

2010

The Pseudosiphona look superficially like a Siphona but with a much shorter labrum. You should also be able to just make out the strong ventral bristle on the katepisternum. Det: Monty Wood, 2010.

Phytomyptera sp. (French Guiana)

Oct

2010

Det: Monty Wood, 2010.

Hypotachina chrysophora (French Guiana)

Oct

2010

Det: Monty Wood, 2010.

Ceromya sp. (French Guiana)

Oct

2010

As you might expect, the siphonines are well represented in the neotropics and familiar genera, like Siphona, Actia and Ceromya can be found. The group is quite easy to determine from the small size, hairy r4+5 (often also r1 and cu) and long, converging or parallel subapical scutellar bristles. Beyond that Monty’s key splits the ...

a genus close to Borgmeiermyia (French Guiana)

Xanthophyto sp. (Bolivia)

Sep

2010

This is quite a distinctive genus – with the shaded rm. It belongs to the tribe Nemoraeini. Determination initially by me – confirmed by Monty Wood.

Trichophora sp. (Brazil)

Sep

2010

Determination by me – confirmed by Monty Wood.

Quadratosoma sp. (Bolivia)

Sep

2010

This is one of my favourites from the batch of Bolivian tachinids that Martin Hauser kindly gave me earlier in the year. Determined by me and confirmed by Monty Wood.

Parepalpus sp. (Bolivia)

Sep

2010

Determination by Monty Wood.

Leskia sp. (French Guiana & Ecuador)

Sep

2010

Leskia is a diverse and quite common genus. Determinations by Monty Wood.

Macromya depressa (Costa-Rica)

Sep

2010

This is a large and very striking fly – Monty Wood has confirmed the genus ID and I made the ID to species.

Jurinella sp. (Costa Rica & Ecuador)

Sep

2010

Determination by myself & Monty Wood.

Jurinia notata & Jurinia sp. (French Guiana & Bolivia)

Sep

2010

Determinations by Monty Wood. EDIT (6/8/2011): After a trip to the BMNH I now believe that the first specimen is probably Jurinia notata.

Epalpus sp. (Bolivia)

Sep

2010

Determination by myself & Monty Wood.

Copecrypta (Bolivia, French Guiana)

Sep

2010

These 2 flies are either Copecrypta or a genus very close to it.

Chlorohystricia sp. (Costa Rica)

Sep

2010

This beautiful fly was given to me by John & Barbara Ismay who caught a few while in Monteverde, Costa Rica, after the 2010 International Diptera Congress. This genus belongs to a very unusual tribe (the Polideini) that look very similar to the Tachinini but that have a very distinctive metathoracic spiracle – made up ...

Chrysotachina sp. (French Guiana)

Sep

2010

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:

Archytas (French Guiana & Brazil)

Sep

2010

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 ...

How to identify greenbottles in photos September 15, 2019
There are a few greenbottle tachinids and one of them (Chrysosomopsis aurata) is incredibly rare so I thought it might be worth showing how to identify it from the others. It is on the wing in late summer so could be easy to confuse for commoner species: Hairy eyes and strong erect bristles on […]
Tachinids that look like Eriothrix rufomaculata August 18, 2019
Eriothrix rufomaculata is an incredibly common fly in mid-summer, especially on any flowery meadows. The species is very easy to identify from the red abdominal side-patches, silvery face with projecting mouth edge, long costal spine, slightly shaded wings with a small petiole on the median vein. The only problem is that several other, rarer, […]
A quick guide to the new UK phasiines August 17, 2019
This year we have been lucky enough to receive records for 2 new species to the UK – Ectophasia crassipennis & Phasia aurigera. These both bear a resemblance to Phasia hemiptera and have been confused with them in the past so I thought I’d put together a few pointers on how to spot them. […]
How to split Tachina fera type tachinids in photos August 17, 2019
One of the most difficult problems is how to confirm/verify the identification of photos of flies that look quite like Tachina fera. I’d include in that group any of the following species: Tachina fera, Tachina magnicornis, Nowickia ferox, Linnaemya vulpina, Peleteria rubescens, Peleteria iavana & male Nemoraea pellucida. They’re all fairly large, bristly flies […]
Dexiosoma caninum vs Dexia vacua August 6, 2019
I always find that one of the hardest identifications to make from photos is the split between Dexiosoma caninum and the much rarer Dexia vacua. Dexia vacua is so rare that many experts thought that it was extinct in Western Europe so getting good, reliable records from photos is very important because it seems […]
