Lady bugs. I liked the subject and the word choice was very nice.

I looked up gilt; gilt is a gold bond issued by the government. Is that what you intended to put there?

"Wandering through time", made me think of a bunch of butterflies, thousands, just billowing slowly onward. Loved it, has just the right words to hit the mark in the heart.

Love does indeed own those dearest pleasures, so it'll require an apostrohe S. Unless the unnamed speaker loves those dearest pleasures, and the line had to be cut short because of form, but I doubt that.

I've never read a sex haiku before. I like it.

The last line is cute and endearing, but I'm not sure what I think about the first. It's outside of your usual finesse, and while I suppose one could make a case for the necessities of tone (or syllabic requirement), 'red bugs' is lacking in imagination, compared to the next two lines.

It's so damn hard to give a meaningful comment on a haiku, yours in particular- it's this perfect package of all the right words and images. You could make a veritable load of cash publishing these on cards with a good illustrator. Meant as a compliment, by the way.

Lastly, as an irrelevent grammatical issue, 'Haikus', plural, does not require an apostrophe, which denotes a conjunction, which it isn't, or ownership, which it doesn't.
