Yes, they have a cover. The epubs display on iPad just fine, calibre shows the cover in its own box, the covers are named cover.png and declared as type cover.
I have a better grasp of epub than of calibe and mobi, though so I either simply convert to mobi and have it copy them via USA to the device using the GUI calibre or do use the shell:
mobi=`basename "$epub" '.epub'`".mobi"; /Applications/calibre.app/Contents/MacOS/ebook-convert "$epub" "$mobi"
/Applications/calibre.app/Contents/MacOS/calibre-smtp -u XXXX -p XXXXX -r XXXXX -s "'$epub'" -a "'$mobi'" SENDER PAPERWHITEEMAIL
