Me and my Indian friend, Priyam were strolling for an walk when we saw a grasshopper on a mantis. No kidding, the mantis did’nt even bother to take the grasshopper of. We gently held it. Nor the grasshopper or the mantis tried to escape. What were these bugs doing??

Mantis and Grasshopper

We believe this is most likely a chance encounter.  Mantids are well camouflaged among twigs and Grasshoppers rest on twigs.  This is a fascinating image.

This mantis has been hanging out on our flag pole for the last 2 days. He is alive, but has been letting a wasp land on his tail for long periods at a time. Now the mantis’s tail is chewed up and half gone. Why would the mantis let the wasp do that?

Mantis

Dear Mike,
We wish you could provide an image of the Wasp.  Generally, when wasps prey upon other insects, it is to feed their young.  We have not heard of a situation where a wasp returns to its prey repeatedly without killing it.

Hi Mr Bug Man,
Please identify for us this bug. We found many of them laying on the sidewalk one day during the monsoon season.

Katydid

Dear Susan,
Your request has been on our back burner since we received it.  Alas, we have tried unsuccessfully several times to identify this Orthopteran, but it does look familiar to us.  It is quite distinctive looking with its gaudy camouflage markings.  Perhaps one of our readers will have better luck than we have had.

Update:  September 5, 2017
Thanks to Cesar Crash of Insetologia who identified this Katydid as
Parasanaa donovani, a species we had in our archives.

Friends of ours down in S. North Carolina had a strange phenomenon this weekend. A long writhing, living, rope of insects in mid-air. None of us have ever seen this before and are wondering A) what these flying insects are, and B) what causes this behavior (mating maybe)?
You guys are great, thanks!!

Mysterious “Rope” of Insects

This is surely a strange phenomenon.  Our initial guess is that they must be Gnats or Midges, and we are going to attempt to provide a more conclusive response for you.  We wish there was more detail in the close-up image.  We can’t even tell if these flying insects have two wings or four wings.  Flies in the order Diptera, the group that includes Gnats and Midges, have one pair of wings while other insects, like swarming Flying Ants, have two sets of wings.

Gnats or Midges????

P.S.  Were they dead or alive?  They appear dead.

They were alive.  I couldn’t get the video he has up on FB, but they are definitely moving.  They are joined somehow, very odd.  Want me to see if they’ll share the video?

Mysterious “Rope” of Insects

No idea what the insects are.  I’d have to see specimens or at least microscope images.

Finally!  I hope these don’t get kicked back due to size.  If so, I’ll throw them up on DropBox and send you the link.
Hope this helps,

Dear Mike,
Thanks for sending in the videos.  Normally we don’t post videos to our site so we hope we did it correctly.  We believe these are Flying Ants, which is what they appear to be in the close-up video.  The wide angle video shows many swarming insects near the “rope” of insects.  Perhaps they have gotten ensnared in the sticky strands of a spider web.

Great, glad you got them!  I looked at it more closely yesterday as well. And I agree, they do appear to be flying ants.
The odd thing is the way that they’re all lined up – you wouldn’t expect to see them as densely aligned in that configuration.
Mother Nature!
Cheers,
M Coughlin
It is our suspicion that two completely unrelated phenomena have occurred simultaneously to create the “ropes” of insects.  There was a swarm of Flying Ants and there was a silken thread, either from a Spider dropping an anchor line for a web or from a Caterpillar that was using a silken thread to decend from a tree.  That silken thread then provided a landing strip for the ants.  We might be incorrect, but that is our speculation.

I’d like to identify the caterpiller (and it resulting moth or butterfly) in the attached photos. It seems to act like a tent caterpiller but spins a strand and drops down to earth. Most strands get wrapped around each other forming a much larger strand (1/4″ dia) that reaches the ground. This site was on a forest road in NE Washington.
Thanks.

Caterpillar Swarm

Dear John,
Since it is green and appears to be hairless, this is most definitely NOT a Tent Caterpillar.  Our web searching for caterpillars exhibiting this behavior in Washington has not produced anything significant, however we did find this interesting article Daily Mail concerning millions of green caterpillars on a single tree.  The site states:  “Stuart Edmunds, from Shropshire Wildlife Trust, said he believed the moths could be the larvae of the aptly named ash moth: ‘It is incredibly rare, when there is a limited supply of trees like there is in this area the ash moth mothers could have decided to lay their eggs all in one place. Usually the caterpillars would be distributed over many more trees and with this many on a few trees there is a danger it could weaken the trees'”  Was the phenomena you observed limited to a single tree?  We feel certain this is a moth caterpillar.  Perhaps one of our readers will be able to help us solve this mystery.

Caterpillar Swarm

Thanks, Daniel.
The site in the photos was all in one tree (which looked rather dry and somewhat bare of leaves).
However, we did see smaller versions of this in two other trees along that same patch of forest. We did not identify the trees the ash moth caterpillers were hanging from.
Maybe others will give us more firm data to add to yours.
Cheers.

My buddy and I have been remodeling my mobile home and after opening up the ceiling we found small square egg sacks .when he reached his arm up in side to move something he has hundreds of bites on his arms they seem to burrow into the skin we are not sure what they are we can’t even identify them because they are so small . We have used standard house spray to no avail. Any ideas

Mysterious Rash

Dear Tony,
We do not have the necessary medical or entomological qualifications to provide a diagnosis based on this image, but that does look like a nasty rash that might need medical attention.  If this was connected to bites, we would suspect some type of mite, perhaps a species associated with rodents or birds.
