This extraordinary insect was discovered in the house, of all places. It is called the Small Snakefly Xanthostigma xanthostigma. This is a female with her long needle-like ovipositor.
There are only 4 species of snakefly in Great Britain under the insect order called Raphidioptera, and in 1 family Raphidiidae. There are 75 species in the whole of Europe, with around 225 worldwide. They are considered ‘living fossils’, as species from the early Jurassic period (140 millions years ago) resemble modern-day species.
The female has a long pointed ovipositor which she uses to lay eggs between cracks in bark. Once hatched, the larvae take around 2 years to become fully grown and are largely predatory on beetle larvae. Adults and larvae feed on other invertebrates like aphids or beetle larvae.
Quite evil looking but glad they eat aphids!

Like many other insects and creepy-crawlies, I am glad they only come in one size! 🙂 Indeed, they can be a gardener’s friend and a natural predator of aphids.

Must admit I don’t think I’ve seen one Pete. Fascinating insect and beautifully caught.

Thank you, Brian. They are rarely seen as they tend to occupy the tree canopy, unless knocked down by wind – or rediverted into my dining room 🙂

In your dining room: you had better make sure there are no cracks in the table legs to provide a home for eggs 🙂 What a remarkable find and such clear, beautiful and informative photographs!

Haven’t seen one so it is a treat to see yours, Pete. Nicely captured. Nothing for us to be frightened of but aphids beware.

Thank you, Steve! 🙂 These are rarely seen out in the field,, yet alone have one drop into your house! Maybe it was looking for aphids, but it was pure out of luck this time 🙂

Thank you very much 🙂 I have only ever seen this twice, and feel quite lucky as they normally are up high in the tree canopy.

It is about 25 mm (1 inch) long. It does grow into a beautiful moth eventually 🙂
