PostForum: General discussion   Posted: Fri Nov 28, 2014 8:06 pm   Subject: Scaeva? ID
Can you see the wing stigma colour?

If yellow, how about Scaeva selenitica.

If black, possibly a Dasysyrphus such as D. venustus or even pinastri (a bit tricky to fully identify). But it is rath ...

I have found that R. rostrata can have a faint dark line around the abdomen sides, but always a lot less than campestris. Although beware of that species occasionally having reduced edge markings.

It's an Eristalis balteatus.

In normal years they are plentiful from early Spring but I have seen few of them this year, until this week when a lot of males have appeared.

Yes, a female.

An odd mark on the hind femur though. Maybe the result of an injury?

Eupeodes corollae looks likely for the first ones. Spots reach the abdomen sides.

Sphaerophoria sp. is the best you can do with females.

The last one looks like Eupeodes luniger to me. The spots ...

Virtually nothing of interest here on the South Coast in dull windy weather.

So far this year, I have found 2 E. balteatus; both in my greenhouse. Or maybe the same one on two occasions. But none e ...

Insects 2 and 3 are Eristalis species. But difficult to be certain of which Eristalis species without seeing other angles.

#2 could be Eristalis arbustorum female but a view of the face would be he ...

Certainly scutatus group. The abdomen length and front tarsus shape appear to be more like scutatus than splendidus. But they are tricky to be absolutely certain.

From what I can see of the wing veins of the first fly, I would say it isn't a hoverfly.

This one looks interesting, Yorkie. I've been waiting for an expert to give an answer! Wink

Melanstoma certainly produce melanic forms, partucularly during cooler conditions. But so do many ot ...

I'm tempted to think, Joan, that this could be Scaeva selenitica (female).

Eupeodes luniger is rather similar but this one appears to have hairy eyes which would point towards the former option.

It can sometimes take a couple of days before anybody gets around to answering questions here; particularly when people are busy sorting through their own sightings.

But someone will always reply, ...

There is a bit of a knack to photographing hoverflies, and most other insects for identification.

I try to run my first impressions through my 'portable computer' (brain) to see if I can come up wi ...
