Hi,
I found a few of these bugs on my work desk where I store hardware stuff. The last time I saw them was when I cut an unused dish washing sponge to aid in some macro photography. They just appeared in a container that held a small insect.
The bug is slightly less than 1mm in size. The thickness of the plastic container rim is exactly 1mm (in the photo).

Springtail

Booklouse

Dear DeepWorld,
This is a Hexapod in the Class Collembola, the Springtails, most likely a Globular Springtail in the Order Symphypleona.  Here is a photo from BugGuide that looks similar.  Springtails are benign creatures that may become a nuisance if they are too plentiful.  According to BugGuide, Springtails are found in:  “Soil, leaf litter, under bark, in decaying wood/fungi, on water surface; some on vegetation. In our area, at least 11 genera include truly aquatic members, >20 genera are regularly found on water surface, and others yet, occasionally. Often found indoors, especially in moist or damp situations such as basins, sinks, tubs, showers, potting soil of houseplants, and windowsills where condensation has accumulated.”

Booklouse

Correction:  Booklouse, not Springtail
Thanks to a comment, we realized that we have once again misidentified a Booklouse as a Springtail.

Hi Daniels,
Thank you for the quick response. I am glad that it has been identified. You guys are great!
Regards,
Walter Loo

Hi Walter,
Actually this is a Booklouse, not a Springtail.

Hi Daniel,
This is exciting news. Thank you for the follow-up and correction! I will definitely read more on this creature.
Regards,
Walter Loo

Found this in my wife’s hair the day after visiting a beautician.
I think it is too small to be lice. It’s super tiny, barely visible. The pic is 100x.
Thank you,

Booklouse

Booklouse

Dear Payton,
We have taken the liberty of removing your surname from this posting as we do not want to draw unnecessary attention to your wife and her hitchhiker.  Though it is commonly called a Booklouse, and though it is classified with Biting Lice in the order Psocodea, Booklice are actually benign creatures that do not bite, but that may become a nuisance when they reach high population levels indoors.  According to BugGuide, Booklice are found:  “worldwide and across NA; many spp. are now nearly cosmopolitan or otherwise widely spread through agency of man, mostly with stored products.”  You can compare your image to this BugGuide image of a Booklouse in the genus
Liposcelis.

Barklice

Barklice

Dear Lauren,
You have no cause for concern.  These are immature Barklice, and they are usually found on trees where they feed on lichens growing on the bark.  There must be lichens growing on your boy’s fort.  Barklice are frequently called Tree Cattle, but in your case, we would have to call them Fort Cattle.

Booklouse

Booklouse

Dear Steve,
This is a Booklouse, a common household inhabitant.  You can compare your image to this image on BugGuide.  According to BugGuide, they:  “are now nearly cosmopolitan or otherwise widely spread through agency of man, mostly with stored products.”  According to the Penn State Department of Entomology:  “Booklice, also called psocids, are not true lice. While they resemble lice in size and shape, booklice feed only on fungi or mold. If you find them in grain or other stored food products, it is an indication of high humidity which encourages mold growth. In addition to food products, psocids may be found under wallpaper, in furniture, along the sides of windows or on window sills around potted plants. Booklice do not bite, transmit disease, or damage food or fabric, but they can be very annoying when present in large numbers.”

Hello, I found these tiny, almost microscopic, bugs in my sink after being gone for the weekend. Any idea what they are?

Globular Springtails

Booklice

Dear Zb,
You have Globular Springtails in the order Symphypleona and though they can be a nuisance when plentiful in the home, they are benign.  They are generally found in damp locations.  See BugGuide for additional information.

Correction:  Booklice
WE just received a comment with a correction.  We concur that these silhouettes are likely Booklice, Liposcelis bostrychophila, as pictured on BugGuide.

Hi,
I’m from Puerto Rico and there are some fun bugs down here in the Caribbean. We recently found this guy in the bedroom and as I reasoned with my wife not to swat it we lost it. What is it? I am including a photo.

What's That Bug???

What’s That Bug???  A Barklouse Perhaps

Dear Antonio,
This has us a bit stumped, and we haven’t much time to research this morning, though we did quickly look at the Insects of Puerto Rico site.  Our initial thought is that it reminds us of a member of the order Mecoptera (see BugGuide) which includes Scorpionflies and Hangingflies, but we might be way off the mark.  Perhaps one of our readers will be able to supply some information.

Update:  Barklouse perhaps
Lepidopterist Julian Donahue wrote in a comment indicating perhaps Psocoptera, and we located a similar looking Peruvian Barklouse on Alamy.
