Bloodworm

Mosquito Project
Location: Grand Rapids, MI
May 1, 2012
Hey Daniel,  You guys were so interested by it last year, I figured I’d just drop u a quick email letting you know that I’m doing my mosquito project again this year. Just started it last week. I’m actually going to be buying a few small fish soon so I’m hoping to be able to raise them for fish food as well. Just wanted to share with someone who shares my passion for bugs!!!
I knew what it was last yr when I did my mosquito project but I forgot what it is. I also didn’t know it goes thru a process much like that of a mosquito until I saw this lil guy with the white beard. icon smile Bloodworm

Hi Amanda,
The aquatic creatures in your photos are Bloodworms: a larva and a pupa.  Bloodworms are the immature phases of Midges in the genus Chironomus.  Here is a matching photo from BugGuide.  According to BugGuide:  ”Larvae are usually found in sediments, and can occur in highly polluted conditions or in relatively clean water. Larvae of the Ch. decorus group, Ch. riparius and Ch. stigmaterus are most often associated with high nutrient/low oxygen conditions.”  Fish will relish Bloodworms as much as they do Mosquito Larvae.

Wingless Soldier Fly in the subfamily Chiromyzinae from Australia

What is this bug? Is it dangerous?

We’ve been finding these bugs all over outside and my little boy has been playing with them. I just need to make sure they are not dangerous since they are all over the place lately.

Wingless Fly: Chiromyzinae species

Dear Autumn and Mark,
In January 2007 we received a similar photo from Australia.  We knew the creature was a fly, but we were uncertain if it was wingless or if the wings were somehow lost.  We eventually learned it was a wingless female fly in the Soldier Fly subfamily Chiromyzinae.  At that time, there was no information available on the internet.  Now we located a Tree of Life web page posted in 2008 that states:  “Chiromyzinae is an unusual group of soldier flies as the larvae are predominantly phytophagous, with many species feeding on the roots of grasses (James 1981; Oosterbroek 1998).”  These wingless Soldier Flies are harmless.

Flower Fly: Helophilus fasciatus

Syrphid Fly?

Hi Bugman,
I was watching a variety of bees buzzing around apple blossoms when I came across this guy. It looks more like a fly than a bee and I think I found the correct identification on your site.
I would like to know if my guess is correct.
Thanks!

Flower Fly

Hi Roberta,
You are correct that this is a Flower Fly or Hover Fly in the family Syrphidae, and many members of this family of harmless flies mimic stinging bees and wasps for protection.  We believe we have correctly identified your Flower Fly as
Helophilus fasciatus on BugGuide.

Thanks Daniel : )
I don’t know how you manage to read so many emails!
Thanks for a great site!

Thanks Roberta,
We aren’t physically able to answer even a small percentage of the email requests we receive.  We cannot even read them all.  We try to choose the most interesting subject lines on days we are unable to respond to many requests.

Mexican Cactus Fly in Elyria Canyon Park

Mexican Cactus Fly
Location:  Elyria Canyon Park, Los Angeles, California
April 14, 2012
After participating in a bird watching hike, Daniel headed home on the path that passes along “dirt” Burnell where four additional lots have recently been purchased and added to the total acerage for the Elyria Canyon Park.  The wild mustard was blooming and this large Mexican Cactus Fly, , did not seem at all concerned that it was being photographed.  Perhaps because the weather was so cool, this member of the Hover Fly family Syrphidae was not as wary as it might normally be.

Mexican Cactus Fly

According to Charles Hogue in Insects of the Los Angeles Basin: “This is a giant member of the flower fly family (its body length is 5/8 to 3/4 in. or 15 to 20 mm), with a shiny smooth purplish-black body’  it is occasionally seen in the spring and summer in areas where cacti grow.  The larvae are large (body length 3/4 in. or 20 mm) pale cylindrical maggots that feed in the rotting, soupy interior of dead and decaying tissues of cacti.”

Bee Flies from Florida

Need Help ID These Bugs?

Can Somebody please help me identify these bugs? I saw the white bug on pine needle and the small one that looks like a fly on this yellow flower.

Bee Flies

Dear ADubin,
We are posting your photo of the Flies on the yellow flower, but we have not had any luck with an identification on BugGuide.  We are not even sure of the family and Flies are not one of our strengths when it comes to identification.  We have requested assistance from Eric Eaton and perhaps he or one of our readers will be able to assist.  Can you please provide any additional information?  When was the photo taken?  What species of flower are the Flies on?  Were there other Flies on other blossoms on the plant?

Update:  Eric Eaton provides an answer.
Daniel:
Sure, these are bee flies (I know!  A very diverse family, Bombyliidae) in the genus Poecilognathus.  Great image!
Eric

Daniel,
All can tell you that I took this photo on April 1, 2012 at 2:30PM EST.  It was in open field that is near a power substation a couple blocks from our house.  In looking at the info on Eric’s Email, it looks like a Genus Poecilognathus – Bee Fly.
Again thanks for your help.

Wanted to share this bee fly with you; I haven’t seen this type around here before, just the little guys; This guy was probably 1.5cm long. I got as far as ’Helophilus’ in a species guess, but past that so many of them look near identical that I gave up in my exact species endeavor.

Hi Katy,
Of the four species in the genus
Helophilus that are pictured on BugGuide, Helophilus fasciatus is the one that has been reported in your area.  BugGuide also indicates that .  This photo from BugGuide looks very similar to your individual.

I spied this unique fly – it looks like a horsefly, but is green. ’can’t seem to find it here on the site. It is not a bottle fly – much bigger.

Chlorotabanus crepuscularis

Hi Melanie,
She, recognizable by her wide spaced eyes, really is a beautiful green Horse Fly,
Chlorotabanus crepuscularis.  Green Horse Fly is a perfect common name for the genus since “Choloro” refers to the color green and Tabanus is a genus of Horse Fly.  According to BugGuide:  “Body pale green, eyes and thorax yellowish green. The only green tabanid in NA.”

The Amazing Replicating Moth?
Location: Washington DC
March 24, 2012 8:45 am
Dear WTB,
So, this particular creature population has been living with us for quite some time- since last summer. At first, they were not much of a problem and we didn’t mind coexisting (especially considering our battle at the time with fungus moths in our plants- ARG!) Anyway, things have gotten way out of control with these little moth-like bugs. Hundreds populate our home on a daily basis. Regardless of whether I decide to kill a bunch or not, they do not seem to live very long to begin with, but always return in greater numbers. I am hesitant to call the exterminator because they charge such ridiculous rates just for a basic assessment. In my searching on the internet, people insist that they are cupboard moths, but they don’t look like them and do not reside in our cupboards at all. They can be found all over the windows, wall and by lights. Our neighbors don’t seem to have them. Do you have any pointers for helping me to understand what they are, how to find the source and take care of them? Thanks.

Bathroom Fly

Hi Travis,
The Bathroom Fly is a common household pest that belongs to the family of Moth Flies, hence your confusion as to its identity.  Indoors Bathroom Flies breed in the sludge that accumulates in drains, and that is where the larvae can be found.  Exterminating the adults will not help with your problem.  You need to get to the larvae.  Pouring chlorine bleach down the drains once a week may help.

Daniel,
You are nothing short of amazing! Thank you sooooo much. I will give your idea a shot and let you know of our progress.  My only question is whether is is more likely that the moths are coming from a drain outside or are they originating from indoor clogged drains? If outside, I am at a loss.  However, they seem to be outside the house often enough. More often inside though, I must admit.  Thanks for your thoughts. Bleach in the drains tomorrow and we’ll see.
Thanks, Travis

Chlorine bleach?!

Daniel:
Advocating the use of chlorine bleach is to my mind akin to Unneccesary Carnage of the environment.  Chlorine is bad stuff.  I wonder if there are less harmful ways to deal with Bathroom Flies? Thanks, Dave Fallow

Thanks Dave,
Many products that we use on a daily basis, including ones to clean our homes, its furnishings and even ourselves, are harmful to the environment, and moderation in our habits is about the best that we can hope to do at this point since so much damage has already been done to this fragile planet.  Perhaps a better response would have been that the Bathroom Flies, though a nuisance, are basically harmless.
