What's this bug?

Post by atikovi »

Noticed this in my yard. About the size of a hornet, 2 inches long, but not a hornet. Looks and moves like a horsefly. Are they aggressive, dangerous or stinging?

Google suggests it's a robber fly, either promachus or asilus. Looks like they eat other resting insects like flies, bees, and butterflies.

Well that's just great, "if they're seriously perturbed, they can inflict a painful bite," If I don't already have to watch out for bees, wasps, yellow jackets and hornets in the yard, now this.

I suggest not perturbing them. :)

Yes; we have Cicada killer wasps around us. They look scary (huge) but unless you really interfere with them they are harmless. They can really do a number on Cicadas. I've seen them drag those for many feet and then into the ground.

There are a lot of things that will give you a mean bite if you get crosswise with them. Many non-venomous snakes come to mind. Some two year old children as well.

I find it easy to avoid snakes and two year old children. Flying insects buzzing all around you, not as easy.

True; but I only worry about the things that are openly aggressive towards people. Around here, deer flies will go after you and ticks can kill you. Ticks I can solve but I don't think anyone has come up with a solution for deer flies.

I bought a device called "bite away" on Amazon which apparently has been validated in a scientific trial as having some effectiveness against insect bites, if applied early. Basically, it heats up the bite area for a few seconds which reduces subsequent inflammation. Mosquitoes are a new thing swarming southern California :annoyed so I'm planning to use it next time I'm bitten. I'll report back on its effectiveness.

Murder hornet: Murder hornets: USA's First male captured in Washington state

This is bad news for bees.

Update: The ID is incorrect. See posts below - it's a robber fly.

Your picture does look at lot like the picture in the murder hornet article. I'd suggest that you notify your local agricultural extension office - early eradication of this pest could be very important.

Well, I'm not allowed to see your picture. I do think the picture posted by the original poster is fairly similar to the one in the link from Lady Geek.

Robber flies are curious about you, but not curious in the sense that horse flies and deer flies are. The fact that the OP was able to get a great photo of this robber fly tells you that it is not a horse fly. :)

Based on the coloration of the legs, it looks a lot more like a robber fly than a murder hornet.

That’s an Asilid (Robber) fly. They are pretty cool. They have excellent vision and snatch other bigs out of midair to eat. They will definitely bite you if you try to handle them (and it will hurt). They will not actively seek you out to attack.

It is not a murder hornet. That’s preposterous.

I had this on my vacation home, property of 89 acres.

https://en.wikipedia.org/wiki/Lipoptena_cervi

Lipoptena cervi, the deer ked or deer fly, is a species of biting fly in the family of louse flies, Hippoboscidae. These flies are commonly encountered in temperate areas of Europe, Siberia, and northern China. They have been introduced to North America.[2] They are parasites of elk, deer, and other deer family members, burrowing through the fur and sucking the blood of the host animals. Adults are only 5–7 mm (0.20–0.28 in) in length and brownish in colour. Their bodies are flat and elastic, making their removal difficult. L. cervi is a poor flier and can only fly for short distances. Once the insect reaches its target, it sheds its wings and starts burrowing through the fur.

Although their life cycle depends on deer, they may on rare occasions bite humans, producing responses ranging from unnoticeable to highly allergic. Initially, the bite may be barely noticeable and leaves little or no trace. Within 3 days, the site may develop into a hard, reddened welt. The accompanying itch is intense and typically lasts 14 to 20 days. Occasionally, an itch papule may persist for up to a year.[3] The main annoyance in humans is the inconvenience and unpleasantness of removing keds from hair and clothes.

Anaplasma phagocytophilum, a Gram-negative, obligately intracellular bacterium that causes anaplasmosis, has been detected in L. cervi, as has Borrelia burgdorferi, the causative agent of Lyme disease,[4] but whether the insect can serve as a vector is as yet unknown.

Why? They are predatory insects that pose no harm to crops, property or people.

Indiscriminately spraying insecticide is foolish as it kills off valuable insects that keep our food supply healthy.

I call them Jerry Garcia flies. If you get a frontal picture, you might understand why.

But yes, they are robber flies. We've had them at our house for years.

I've come within 5-6 inches of them, but have never been bitten.

I identify insects by looking at form in addition to color. The "tail" was very close to a murder hornet.

Looking at this harder, I agree it's a robber fly and have updated my earlier post.
