What is this?
Dear WTB,
please help me identify this bug, we live in Norfolk in the UK and it landed in our garden, on a hot sunny day this July. The only thing I have found that is similar is a ‘Hornet Robber Fly’ but it has a different body and yellow eyes. > I look forward to hearing what you think it might be!
Rgds,

Hi Matthew,
We are unfamiliar with the English species, but this bears an uncanny resemblance to a Horntail, a type of wasplike insect in the Family Siricidae. They have cylindrical bodies with the thorax and abdomen broadly joined together, not separated by a waist. In females there is a stinger like ovipositor which is used to drill into stems or wood where eggs are laid. Adults feed on nectar.
