Greater Bee Fly

Greater Bee Fly

Dear Susan,
When the common name for
Bombylius major was given, someone noticed that this True Fly had some physical traits that resembled those of a Bee, hence the moniker Greater Bee Fly.  Indeed, the scientific binomial shares an ancient root with the tribe of Bumble Bees which is Bombini.  The Greater Bee Fly is also found in Europe, including the UK, and it is unknown to us where the species originated.  Your interesting subject line really caught our attention. BugGuide has this description of members of the Bee Fly Family Bombyliidae:  “Hairy, often brightly colored flies. Legs usually slender, Wings often have dark markings, held outstretched at rest. Face not hollowed out. Eyes almost touching above, especially in males. Proboscis either short with broad tip, or long and used to take nectar. Hover and dart, rather like syrphid flies. Females sometimes seen hovering over sandy areas, dipping abdomen to oviposit.”  Additional information on diet includes:  “larvae are mostly external parasitoids of holometabolous, esp. soil-inhabiting, larvae (Coleoptera, Hymenoptera, Lepidoptera, Diptera), slowly consuming the host completely without making a visible wound; a few are endoparasites, predators (esp. on grasshopper eggs), or kleptoparasites; adults take nectar/pollen” and the life cycle is described as:  “larvae undergo hypermetamorphosis: 1st instar larva is active and penetrates the host’s nest, then turns into a sedentary parasitoid; pupa is equipped with spines/spikes to drill out of the nest.”

Hello Bugman,
I’ve seen this insect for 2 days so decided to get some pictures! I have never seen anything like it and can’t indentify it from the internet.
It appears to have a ’sting’ or solid long thing coming from it’s head.
It has been seen 7th April and 8th April 2013 in Bedfordshire, England. Both times it was around 2pm
Please can you help?

Greater Bee Fly

Dear Mrs B,
Your insect is a Greater Bee Fly,
Bombylius major, and it is found “throughout most of NA (Canada and the US to Baja) and Eurasia” according to BugGuide.  The Greater Bee Fly is a harmless pollinating insect that uses its long proboscis to take nectar from flowers.  You may also read about them on UK Safari.

We found this fella feeding on suflowers in South Texas. Long longs, long proboscis – definitely designed for feeding on these flowers. Can you identify?

Bee Fly

Bee Fly

Dear Tim,
This is a Bee Fly in the family Bombyliidae.  We would prefer to leave a species identification to a Dipterist or someone else who specializes in the family or order.  Bee Flies are pollinating insects and you can read more about them on BugGuide.  It appears this might be a member of the genus
Bombylius, but often superficial visual similarities exist across genera.  You may also read about Bombylius on BugGuide.

I see these around my yard all the time. They are super fast! & Super small! They remind me of hummingbirds how they fly, and they will not allow me to get close before they zip off out of sight. Are they flies? are they bees?

Bee Fly

Dear Texas Finest,
This is actually a fly.  Flies are distinctive among insects as they have a single pair of wings while other flying insects have two pairs.  Your fly is in the family Bombyliidae and the members are commonly called Bee Flies because they resemble bees.  Your confusion is understandable.

Right now we haven’t the energy to identify this relatively large Bee Fly in the family Bombyliidae to the species level, but we invite our readers to scour BugGuide and send us anything they discover.  This is the final photo we took this morning.

I’ve seen these insects in flowers in our yard and assumed they were bees. Today I came across a mating pair and took photos, and after searching here and at BugGuide, I think they may be Bee Flies or Bee Mimics? The one on the right kept trying to fly away, but the one on the left just kept dragging the other one along from place to place.

Mating Bee Flies

Hi Karen,
As we frequently do when we need to research or verify some North American bug, we turned to BugGuide where we identified these mating Bee Flies as
Poecilanthrax lucifer.  According to BugGuide, “The larvae feed on the moth larva of members of the family Noctuidae.”

Hi! I just found your website and it is heaven to a bug lover like me.
I’m hoping that you can ID this fly for me… thanks!
Signature: If new, do I get to name it?

Scaly Bee Fly

Dear If new, do I get to name it?
This is either a Scaly Bee Fly or another member of the genus
Lepidophora.  The process for naming a new species is rather involved and generally includes publishing a technical paper describing the species.  You may read more about the genus on bugGuide which includes this information:  “Larvae are kleptoparasites of solitary wasps (Vespidae, Sphecidae)”.  True Parasites feed off of a host.  Kleptoparasites eat the food supply provided for the host by its parents.

Thank you for your response! I tried looking through your database, but couldn’t seem to get to the right area.

Sorry, to bother you again, and thank you for answering my last inquiry. There are these flies/bee things here and they are soooooo big. No clue what they are, could you please see if you can help me out again?? I thought maybe horse/deer flies, but nothing is as big as these are. The pics don’t do the size justice. I shouldn’t have zoomed in, but I wasn’t getting close lol

Tiger Bee Fly

Hi Julie,
This Tiger Bee Fly,
Xenox tigrinus, is perfectly harmless.  According to BugGuide it is:  ” A large Bee Fly with a distinctive wing pattern. Note the large, wrap-around eyes.”
