Beasts from the North

During my trip to the Scottish Highlands and the Lake District I managed to take some photos of some insects I have never seen before.

Tababus sudeticus 4

This is the dark giant horsefly Tabanus sudeticus – a female nearly an inch long! Fortunately it prefers the blood of cattle and horses to people. Saw one individual at Castle Urquart on Loch Ness and this one was taken on the National Trust property Aira Falls beside Ullswater.

Tababus sudeticus 1Substantially bigger than the horseflies (normally Tabanus bromius and autumnalis) that I have seen before

Tabanus sudeticusIt has been recorded in Devon and on Dartmoor but I have never seen it.

Trichius fasciata 1Second up is a beetle – one of the chafers Trichius fasciatus – known also as the bee beetle or bee chafer. Its one of those animals you see in the books because it is so spectacular – finally I have seen one in the wild. Saw it at Loch Achilty, north west of Inverness in the Highlands. A Forestry Commission site.

Trichius fasciata 4A really striking beetle with long brown hairs on the thorax.

Trichius fasciatusOnly really recorded in the UK in the Highlands and Wales.

Tachina grossa 4

Finally another fly and another big species – its called Tachina grossa – or the yellow faced fly. It is very striking and large – nearly 3/4 inch long.

Tachina grossa 1The female lays here eggs on the larvae of other insect larvae – often an oak eggar moth – which the hatched maggots then devour and kill!

Tachina grossaA more cosmopolitan species – again on Devon and Dartmoor – one to look out for – unmistakable.
