Better still, I began to get a sense for the entire family: what conditions its members like, what characteristics mark the family itself or help you sort out its members. In short, I learned something! I find this fun.

It is now widely established — so widely, in fact, that it may be out-competing many of our native ladybugs, such as the two-spotted ladybug that is the official state insect of Massachusetts. (I bet you didn’t even know we had a state insect!)

I could go on for weeks about the various approaches plants take to make adversity less adverse. Here are just a few examples to illustrate how creative evolution has been.

To be sure, there are a few species of each that are irritable enough to make awkward neighbors. The so-called social bees and wasps, that is, the species that live in large colonies and build elaborate nests, certainly will sting in defense of their homes. (Wouldn’t you?)

Why do moths come to lights?

The Vineyard supports good numbers of bog coppers, but this unique butterfly depends on keeping local bogs healthy.

Which is pretty remarkable when you think about it: to form a gall, an insect species must develop the ability to hijack the biochemical processes that govern tissue production in a plant, producing a structure that perfectly suits the insect’s needs.

The juniper hairstreak is fairly easy to find, and very much worth the effort. Its underside bears an elaborate pattern of stripes. But this species is distinctive because the basic ground color of its wings is olive — it is the Island’s only predominantly green butterfly, and fresh ones, especially, are stunningly beautiful.

The relationship between humans and Cooper’s hawks has not been a happy one. The hawks, being optimized for bird-hunting, have a hard time passing up chickens. And farmers, not wanting to lose chickens, for many years responded by shooting the hawks.

They’re neither helpful nor harmful from the human perspective, and their disappearance would likely have little ecological effect. But I value my acquaintance with them: knowing these insects, I feel like I have a secret perspective on the Vineyard landscape. And the season’s first Juvenal’s duskywing, bopping across a path or clearing, is always a welcome sign that spring is here to stay.
