Linnaemya picta – male genitalia

Linnaemya picta was added to the British list fairly recently but has been found in a few localities this year – namely Kent, Suffolk & Cambridgeshire. There was also a suspected record from the Reading University grounds but this wasn’t confirmed beyond doubt. So it is worth noting that the male genitalia are particularly distinctive, […]

A typical tachinid wing

This is a photograph of a Tachina grossa wing, annotated to show the commonest features that are used in the keys:

I always orient myself by looking for the smallest vertical vein called r-m, the little one in the middle – it links the last true radial vein (r4+5) to the median. The median vein […]

Some tachinid head close-ups

Here are a few of my latest stacks showing some nice tachinid head close-ups. Most were all taken using the Nikkor EL 50mm f2.8 lens reversed on bellows 🙂

Some Siphona… and Pseudosiphona

These are a few photos of Siphona spp. in my collection. A few of the identifications, like boreata and maculata, are easy but the others need confirmation because the genus is very difficult and I still haven’t got to grips with them. The specimens were actually taken abroad – in Finland.

The Pseudosiphona is neotropical […]
