Episyrphus balteatus (De Geer, 1776)

So I've been generally avoiding posting ridiculously common and widespread species, on the basis that they're already all over the internet and you can see a thousand billion pictures of them (possibly an exaggeration) at the click of a button.

But as much as this insect is no Synagris proserpina (only female pictures on the web, only full colour pictures of (admittedly deceased) male, as far as I can tell) or Megistocera filipes filipes (only photographs of this subspecies on the web currently mine, including those featured on the Catalogue of Craneflies of the world), and by its cosmopolitan distribution, is quite un-exotic by anyone's standards,
this makes it worth it:

Episyrphus balteatus, Bosham, West Sussex, UK
Next time, I'll use a full flash to escape that grainy background, but for now, I'm proud of myself.

Seeing as we've started with the photo, we may as well do the rest in reverse order:

Our un-mysterious guest today is the marmalade hoverflyotherwise known as

Note - 'previously featured' lists are links to other pages on this blog posted prior to this page, and species are listed at the most recent node that appears in their own taxonomy. It does not mean that the taxon no longer includes those species. Just in case it wasn't clear. 

One final tidbit, just so you have some idea of what this insect looks like beyond its massive eyes: 




Note 1: 

In the light of one of my recent visitors having found the blog by searching 'What does Episyrphus mean?' in Google (I believe), Syrphus in this instance refers to the common European hoverflies in the genus 'Syrphus', the original meaning of which is unknown to me, but I suspect Fabricius derived it from the latin for up (~sursum) and possibly the noun for "flight" (~fuga), or possibly the 'Phus' was just to be in keeping with existing names, creating a noun form. The 'Epi' means after, or in association with, as in 'Epilogue', and 'Epinephrine' (After-speech and Next-to-kidney, respectively). As such, Epiyrphus means Next to Syrphus, which itself means Up-flier. Probably.

Laelia cf. robusta, Janse, 1915

I'm not dead, honest! Just working for minimum wage... so taking as many hours as possible to earn enough to pay rent.

Hopefully you've noticed the cf. (confer, click for wiki to tell you more, Latin, common abbreviation typically meaning that it's similar to the names species, but may not in fact be it). This is largely because the genus Laelia is huge, and I don't have the time just currently to search for an rule out every species. 

However, on the basis that the Laelia moths I have looked at all look quite variable, and in most moths external appearance is quite an important identifying feature, I'm going to venture reasonable confidence that this is in fact Laelia robusta.

So, without further ado, on with the show:

Laelia robusta
Janse, 1915

and here it is:   


Laelia cf robusta, Chongwe, Lusaka, Zambia

 I apologise for the rather characterless portrait - it had a special talent for hiding its face with those spindly forelegs and a vast amount of facial hair. Photographed in Leopard's Hill, Lusaka, Zambia, in March 2013.


NOTES: Species is suggested based on comparison to images of alleged L. robustahere (a flickr image, captured and presumably identified by Geologist Nigel Voaden), and, by its being featured on the apparently reputable Afromoths page for this species, reliably identified).
