...Sequel
IX is– kind of - logical following to our previous post (;the sequel VIII from beetles).
I've not too much rearranged these posts, or, seeked to find any
especial proper species presented on these. So, similarly than was
the manner on previous sequel, I just picked a few
suitable examples as decoration of this.
This also not contains any particular views from the insect evolutionary
pasts, for it was (but briefly) discussed in the previous sequel.
Perhaps we can only on this notice that the so called 'modern' insect
orders evolved (smtgh like, approx.) about +/- 200 M. years ago to
the past. Mostly that took place along the evolution of Angiosperms
(ie the flowering plants, whose appearance closely was interactive and co-dependent within the insects evolution).
This (to the right) is some from the nicest Hover-/Flowerflies (Syrphidae). There's about 250 species at Fennoscandia ranges, of various sizes and looks; Some are quite 'robust', some lot smaller and thinner. Most, at least from the easily noticeable species, seem mimic the looks of wasp/bees.
Basically,
suffices (at this) if we only refer for the other main three orders usually described for the 'modern insect families'. (Seems that) them all did evolve along the appearance of flowering
plants. Of other large groups, there's Beetles (...presented
already on the previous sequel, but them are said also represent the
largest insect group in the world by singular species). Then is
Lepidoptera (Moths /Butterflies which also have been quite
much represented on our previous posts.) Then, Hymenoptera (Bees,
Wasps, Sawflies, Ants, etc...) which I actually considered
possibly the insect group on this post ...but then I realized there are
very numerous species and they're much resembling each other. So, fx many Bumble-bees that have Fennoscandian presence look quite similar and I
therefore decided drop them aside. Leaves us the Diptera – ie
the Flies (although that
contains some other related genera too).
"Fly on the wall" (To the left) - Similarly than from the most larger insect groups, there's both flower-going and predative species on flies. This is predative (from Rhaginiodae). Often found closer swamps and some shallow wetland(s).
Among the
most renown of (actual) flies in the world, probably, is Tset-Tse
(Glossina sp.), a blood-sucking species at the mid-Africa that
spreads the Sleeping sickness disease. (More precise, it
carries the small Tryponasoma-parasitoids, that spread the
sleeping sickness. Often fatal disease for the domesticated animals
and can influence the humans badly too. The disease doesn't influence the wild animals, so the Tset-Tse fly is sometimes on ecologist
literatures been described as the 'best conservation
agent' on Africas, due it long time prevented human agricultures and cultures from reaching
large regions at continent. Although, some other tropical diseases
such as malaria and dengue also are often mentioned having appeared so commonly that some places remained inhospitable to the Europeans
and outside their colonial interventions well until the 20th
century. Anyway, actually there exists a so called Tset-tse-belt
accross middle parts from Africa.)
Then, there's at least the Common House-fly (Musca domestica), sometimes described for the most widespread insect species in the world – to most places where's humans it also has spread. Like was noticed typical for the flies, it is also been said from having a considerable role at the spreading of some diseases, stomach-related mainly.

...This by somewhat resembles what most people would describe as typical outer looks of a fly (ie the House-fly). (But this belongs at the Sarcophagidae, most common species on forests. There's about, 35 Fennosc. species from those, solely.)
Usually most flies are felt with some remarkable disgust by humans, generally. In addition, many species show quite 'horrifying' from their appearance (w. their large compound eyes and hairy outer looks). Some also (often) tend increase and swarm on the rotten smelling carcasses and dung. Not all flies show such detestive manners, but a typical place to find amount of flies, is fx a heap of manure on some swineyard backyard. Them are also often mentioned from spreading various diseases, like was mentioned. (...Remembering the above said aspects it's also perhaps not too surprising that some from (a few) successfull remakes from old horror-movies on the recent decades features fly as it's main 'character'; I mean that David Cronenberg film - sometime at 1990s by the same name, Fly, if I recall that correctly. As you might remember, it has a Frankensterian plot from the scientist who invents some transmutative machine and – by accident – happens to unite his genes with those of a House-fly.)
However, or
from the positive side, flies also have other qualities than the
repulsive manners that usually are given most concern. Some are fx
very competent fliers; Watching the various Syrphid-flies (see
exemplary species above) when their visiting some flower bush, one
can easily recognize that. They can fx remain practically motionless
on air, except from the wings goin' on. (Not
very surprisingly the Syrphids (Hover-/Flower-flies) are
probably the most easily tolerated flies of the human perspective.) Then there's other species
that on fast flight can make about 90'angle turns, not the least
difficult of tasks at flight for sure. (Also not very surprisingly,
if one thinks the common names for many insect groups – most,
although not all – seem carry naming that refers for the flies /or, for
flight. There's fx Butterflies, Caddisflies,
Mayflies, Dragonflies, Snakeflies,
Scorpionflies, Craneflies, etc., ….So, for an
observer it soon becomes clear how these flying creatures
were named in the first place, or which probably were the first
recognized insects by humans. Although, not on all languages they're
so uniformly or similarly.)
(To the right) Laphria flava (..likely). ; It's from the Robber flies (Asilidae), that are among the most 'hideous' of the pretative species. Completely harmless to humans, but on the insect world it's respectable player; The robber flies are said capable to force down large beetle off the flight, and biting through it's protective cover-wings. Also, them can deliver poisonic bite (dealy to other insects), so even a wasp is for 'no match' (...albeit, I see no reason why they'd hunt those). (...Robber flies are species adapted for the sun and warmth, so their less numerous on Fennoscandias. At the past decades were somewhat declined...and some species, at least, seem still listed for threatened.)

In the the Diptera (all in all, including also fx the Crane flies and Mosquitos) there appears about well over 5000 species on Fennoscandia range - or, probably somewhat more by now which are been recognized as the separate species. Of course, far more could have been presented at this sequel. With the far more particular characteristics presented, far more detailed descriptions, etc., etc., ...but let's (for now) call it quits from this sequel. (;W-G.)
(To the right) ...Some species with a quite exciting elongated looks too. On leaf of a Birch (Betula pendula). Apparently - but far less usually than some other insects - there's flies that lay their eggs on plant leafs. (Or, likely so I'd guess). However, many favor the decayed wood, also.
