Spider Pictures on lawn -in plants
These are the spiders I wrote you about yesterday, as you can see they are all over our porch, plants, and lawn. Thank you!

Hi Beth,
You have Grass Spiders, Agelenopsis species. They are found in grassy areas and low shrubs and near buildings. They build a horizontal sheet web with a funnel extending from the center to one edge. They run quickly when an unlucky insect stumbles into the web. The webs become very obvious in the morning when covered in dew. Nice lawn photo.

Big Icky Bug
Hey Bugman,
I am a student at Palm Beach Atlantic University here in West Palm Beach, Florida . One night not too long ago I was walking a young lady home and came across this monster looking beetle. I have never seen anything like it before in my life. After I convinced the young lady to stop screaming and even get a closer look, I snapped this picture with my phone. I’m sorry that the quality is not all that good. I tried to buff it up a little as far as the lighting goes but I didn’t want to alter the photo too much. Could you please tell me what in the world this beast is? I have asked several native Floridians and no one seems to know.
Yours truly,
Fred G. Krauer, Jr.

Hi Fred,
This is the infamous Toe-Biter, the Giant Water Bug, Lethocerus americanus, which is also known as the Electric Light Bug because it is attracted to lights. The common name Toe-Biter needs no explanation for anyone who has been bitten while swimming in a lake. The bite is very painful. These bugs are aquatic, but equally well adapted to flight. On land they are rather clumsy.

What is this?
Dear WTB,
please help me identify this bug, we live in Norfolk in the UK and it landed in our garden, on a hot sunny day this July. The only thing I have found that is similar is a ‘Hornet Robber Fly’ but it has a different body and yellow eyes. > I look forward to hearing what you think it might be!

Hi Matthew,
We are unfamiliar with the English species, but this bears an uncanny resemblance to a Horntail, a type of wasplike insect in the Family Siricidae. They have cylindrical bodies with the thorax and abdomen broadly joined together, not separated by a waist. In females there is a stinger like ovipositor which is used to drill into stems or wood where eggs are laid. Adults feed on nectar.

Can you identify beetle
I hope you can identify this insect, I think beetle, but not leaf beetle. The above photo shows it to be 3/8 inch. The below photos shows a pair (mating?). My location is San Luis Valley, Colorado. 8,000 ft elevation. Very arid. I first saw them at our creek on tumble mustard. A couple a days later they arrived in the garden 500 feet away on the horse radish leaves (probably 100). There are only a couple on the potatoes which are next to the horse radish. None on any other garden produce. Any ideas? Are they harmful or beneficial? What can discourage them? Thanks,

Hi Dave,
These are winged adult Harlequin Bugs, Murgantia histrionica. They do feed on mustard in vacant lots and fields. When they move to the garden they infest cabbage, kale, collards and related plants. The best control is to locate the eggs which are barrel shaped and in rows. Hand picking will also do the trick. Also, when your crop is harvested, immediately remove any remaining plants that serve to perpetuate the infestation.

I know these pictures are not the greatest but it’s the best I could do at the time. This is what I know to date: I live in Detroit, MI. I have seen about 5 of these in our area. I have lived in MI my entire life 45 years and in this house location for 10 years and I have never seen one of these bugs or their tunnels in the area. They tunnel in the dirt that is between the sidewalk and the grass. Their tunnels seem to always be on a 45 degree angle through the dirt. They mound the dirt up outside the tunnel, it’s a huge mound about as big as my shoe. Could you please help in identifying this creature? Thanks for your help.

Hi Byron,
I hope this Cicada Killer met a death by natural causes. The Cicada Killer, Sphecius speciosus, is a large solitary wasp. A female digs a burrow and provisions it with cicadas. The cicadas are often larger than the Cicada Killer. She stings the cicada oftne in a tree, and then flies down toward her nest while carrying the large cicada. If she does not reach the burrow, she climbs another tree lugging the cicada and then attemps again to fly to the burrow. The cicada is only paralyzed by the wasp and once the cicada is buried an egg is layed. When the larva hatches, it feeds on the still living cicada, a source of fresh meat. I would guess that an unusually large population of cicadas in your area this year is also responsible for the increased numbers of Cicada Killers.

What is this bug
I have been surfing the internet trying to find out what this is. I have it live in a baggy with its dead fly it was eating. It seems very aggressive towards me when I move the bag. It was in my garden window.

Hi Sharon,
Great photo of a Robber Fly, Family Asilidae, preying upon a Green Bottle Fly. Robber Flies are common, swift-flying predators. They pounce upon resting insects from above and use the short, strong proboscis to drain their prey’s body fluids, according to the Audubon Guide. On a more personal note, please release it. Sharon, you would act aggressively if someone put you in a bag, wouldn’t you?
