Tiny yellow insects that are hard to see, they fly around, rest on windows, and wehn they land on you they?

Question

feel like a flea bite or gnat bite. They just showed up in our neighborhood. Does anyone know the name of these insects?

Answer 1

Difficult to know without more description (shape, walking speed and action, size).  There are thousands of types of insects!

Do they actually bite, or just tickle as they walk about on your skin?

Could perhaps be aphids ("greenfly").  These walk slowly, are rather clumsy fliers, and suck plant juices -- but don't bite humans or other animals.  Usually about 2 or 3 mm long.  Some are green, some yellowish, some purplish black, and some produce a waxy wool when feeding.  In many species only some are winged, while others remain on the plant feeding and breeding.  Species whose food plant happens to be a crop or garden plant can be pests.

Or what about psocids, or "booklice"?  Again some are winged, some not.  Most species are brownish or yellowish, and very small (1 mm or less), though there are some larger ones.  I think the ones in houses mainly eat mould -- sometimes seen as pests, but don't really do any harm.  Many species, some in houses (usually without wings), many on plants.

Another possibility might be thrips, or thunderbugs.  Again, many species, and some are pests of crops.  Can be various colours, but usually (when I've seen them here in UK) blackish, long and narrow, perhaps 1 or 2 mm.  Often inside windows in hot sultry weather, and very ticklish indeed on damp skin.

Search for images of these and see whether any look right.

Edit:

I agree that they could be leafhoppers -- were they as big as that though?  These'd be about 3 or 4 mm at the smallest (much smaller as babies, but those don't have wings).

Answer 2

They're called aphids. The other day when i was working outside, i was getting covered in them. I agree with you, they feel like they bite, but its just their prickly legs. Take a scolding hot shower to kill them if you cant find them on your skin.

Answer 3

No-see-Ums.  Really thats the street name.

Answer 4

sweat bees or no see ums.  Sweat bees are tiny yellow bugs that are attracted to sweat and bite hard.  no see ums are little tiny nearly invisible bugs that also bite.

Answer 5

I think they are Leafhopper....

Leafhoppers are found all over the world, and it is the second largest family in the Hemiptera; there are at least 20,000 described species. Leafhoppers have piercing sucking mouthparts, they feed on plant sap and can transmit plant-infecting viruses and bacteria. Species that are significant agricultural pests include the potato leafhopper, beet leafhopper, white apple leafhopper, two-spotted leafhopper, and glassy-winged sharpshooter. A Leafhoppers' diet commonly consists of plant sap from a wide and diverse range of plants. Leafhoppers mainly consume vegetation but have been known to indulge in small insects such as eepids
