A couple of days ago, Val (Plot 23) had the pleasure of encountering a beautiful Giant Horntail on her allotment. For those who may not be familiar with this fascinating creature, here is a bit about the experience and why it’s such a special sight.

At first glance, the Giant Horntail can be quite an alarming sight, especially for those who are not particularly fond of insects. Measuring an impressive 15 cm or more, its size alone is enough to catch anyone’s attention. However, it’s important to reassure everyone that despite its formidable appearance, the Giant Horntail is completely harmless.
It does not sting and poses no threat to humans.
So, if you happen to spot one, please do not harm it. These insects play a vital role in our ecosystem, particularly in the decomposition of dead trees, which helps maintain the health of our natural environment.
How to Identify a Giant Horntail
For those interested in identifying this magnificent insect, here are a few key features to look out for:
- Size: Giant Horntails can grow to be over 15 cm in length.
- Color: They typically have a dark body with yellow markings.
- Wings: Their wings are clear with dark veins.
- Tail: The most distinctive feature is the long “horn” extending from the abdomen, which is actually an ovipositor used for egg-laying.
