Introducing Matt Harrow | Identification Trainers for the Future

The next new trainee from our Identification Trainers for the Future project is Matt Harrow. Matt has a passion for a subject many may not initially share – Diptera (the true flies), but having started out identifying the more charismatic hoverflies, his interest quickly extended to some of the more unusual groups within this diverse and fascinating Order and he hopes to pursue this interest through the traineeship with the help of our colleagues in the Diptera team.

I can’t remember a time when I haven’t had the urge to get outside and see the wonders of the natural world. For the most part my forays into nature have simply focused on being in the landscape with next to no interest in the smaller things; the plants, birds and insects which do in fact make the place what it is.

It was only whilst studying for a degree in countryside conservation at Aberystwyth when I really started to look at the bounty of life all around. My final year project was decided after scrolling through social media and seeing all the wonderful photos people had posted of Hoverflies, after a few emails to the recording scheme organiser I had a solid title and lots of data to play with! The only problem now was that I knew next to nothing about this fascinating group of flies so off I embarked on some serious reading, realising soon enough not only the vast amount of information there is to take in but also how much is unknown and the opportunities for discovery.

The flies that use their eyes to fight for love… well, sex at least | Curator of Diptera

Before the Museum exhibition about Colour and Vision closes on 6 November, I thought I should write a piece about some of nature’s most amazing eyes (their patterns and shapes). I’m talking of course about those belonging to flies – the most enigmatic of all species on the planet – and specifically all the species referred to as stalk-eyed flies.

My first experience of stalk-eyed flies came while I was carrying out fieldwork in Costa Rica over 10 years ago and it can probably go down as one of my favourite fieldwork moments. So what happened?

Tabanidae – horseflies | Curator of Diptera

Once more I am writing in defense of some very attractive but much-maligned creatures that, due to the maternal habits of the females, are universally disliked. People scream, run, swat them with wild abandonment to stop these ladies from providing essential resources to enable them to produce their next generation – it’s not very nice of us to let them get food for their offspring!

Yes, Tabanidae, or horseflies to give one of their common names, are some of the most painful biters of all flies but, like their also very much-maligned cousins, the mosquitoes, the males are vegetarian and can also be very important pollinators (e.g. Philoliche species found in South Africa – see the reference in one of my older blogs).

#WorldRobberFlyDay 2016 | Curator of Diptera

2015 saw me launch the inaugural day of celebration of all things robber fly so, on this 2nd #WorldRobberFlyDay, here’s a quick spin through the best of last year’s event:

 

 

And take a trip to Twitter to see what’s happening this year.

What’s in a fly? Musca domestica – the greatest traveller of them all | Curator of Diptera

Within the Diptera section we are asked a lot about individual species of flies and so we thought we would put pen to paper (or key to board) and give some species descriptions of the more popular requests.

My co-author for this post, Nigel Wyatt, is the curator of all things bristly (including his own, he adds!) such as some of the most well known of all Diptera – the houseflies. Often seen as the greatest nuisance to humans and animals, this tenacious species has travelled with us all over the planet and enjoys all the creature comforts that we provide for it!

#WorldRobberFlyDay | Curator of Diptera

OK, I have decided to create #WorldRobberFlyDay. All the time now, we hear that this large mammal or that large mammal has a ‘day’, and that got me thinking. Buglife have an Invertebrate of the Month, but even they are not very often the lesser-known insects, including the flies.

And I wanted global. Let the world celebrate! Why is it always the large stuff or the pretty (and, in my opinion, slightly less important) species? So I thought about it and decided it was about time that we championed more aggressively the rights of the small and endangered flies. These creatures are some of the most charismatic animals on the planet. The robberflies, or Asilidae, are truly worth celebrating for their looks, for their behaviour, for their good deeds to us, and because many of them are threatened.

The UK boasts 28 species of Asilidae (OK, so that’s not a lot in terms of flies, but hold on – we have only 30 native terrestrial mammals, of which 17 are bats and 2 are native marine mammals). Globally there are more than 7,500 species, and as such, it is one of the largest families of insects today. In fact Torsten Dikow, a world expert on this group, has them as the third most speciose group of diptera. This is a group, therefore, that has a large impact on the environment in which they live.
