from Easton's 1897 Bible Dictionary

Gnat
only in Matt. 23:24, a small two-winged stinging fly of the
genus Culex, which includes mosquitoes. Our Lord alludes here to
the gnat in a proverbial expression probably in common use, "who
strain out the gnat;" the words in the Authorized Version,
"strain at a gnat," being a mere typographical error, which has
been corrected in the Revised Version. The custom of filtering
wine for this purpose was common among the Jews. It was founded
on Lev. 11:23. It is supposed that the "lice," Ex. 8:16 (marg.
R.V., "sand-flies"), were a species of gnat.
