Green spears

The species tulips with the leaves of a lighter green are now appearing. I think that usually they appear before the tulips with the darker-green leaves. Of course, I don't remember which kind is which; one is definitely Lilac Wonder and the other, mostly Tubergen's Gem. Hyacinth leaves are now appearing in more places. There are still only the two blooming stalks of paperwhite narcissus. Everything else in bloom is left over from an earlier time of year: geranium, fennel, nasturtium, asclepias, and chile. And there are still loquat flowers open because they've not yet been pollinated. Everywhere there are green lacewings. Have they propagated themselves? Or did someone release some at this not-great time of year?
