I went to Avalon Nature Preserve in Stony Brook last Monday. Not that I ever need a reason to visit Avalon, but I was hoping for some butterflies and maybe a bird or two. I failed on the birds, and most of the butterflies as well. However, I did have some luck with one very small butterfly. It is indeed tiny, maybe only about the size of my thumbnail. I was lucky to have spotted it at all.
This is one very cool butterfly. It’s called a Red-banded Hairstreak. Many species of butterflies have false eyespots on their wings. Most scientists believe that these eyespots serve one of two different purposes. Some use these eyespots to intimidate possible predators. A large eyespot implies a larger animal, one that may be too big for that predator. Other butterflies use their eyespots as a form of misdirection. An eyespot towards the rear of the butterfly may help convince a predator to strike at a less vulnerable place than the butterfly’s head, which would be most unfortunate indeed.
The Red-banded Hairstreak uses the second method, but it ups its game a bit. Its wings form a “face” of sorts that is only seen from directly behind the butterfly. But the trickery doesn’t end there. This butterfly has another ace up its sleeve, or, well, wing. By rubbing its hindwings up and down against each other it causes the two little tails to undulate in a manner that mimics moving antennae quite effectively. Even in a still photograph, you can see how realistic those two fake antennae appear. Now, imagine those two antennae moving in a probing motion like true antennas. It’s a very convincing trick and helps this tiny butterfly escape the local thugs.
And need I mention how beautiful this butterfly is? JK

This is a male Slaty Skimmer (Libellula incesta) that I encountered at Frank Melville Park in Setauket. Of course, when I took this photograph, it was just a big blue dragonfly to me. Luckily, we here at Joe Kayaker have a dragonfly expert on staff who was able to ID this guy for me. My friend Annette has been identifying dragonflies for me since 2014. Besides being a bonafide dragonfly expert, Annette is the author of several blogs. You may want to check them out as she is also an excellent photographer. There’s lots of eye candy in her blogs. JK.

That amazingly beautiful flower is called Lupine. I only know that because my friend Sue Avery identified it for me. Sue was also able to explain to me that this is considered a single flower as opposed to several separate flowers. She added that a flower of this type is called a Raceme. Racemes are clusters of flowers that grow from the same base. So what looks to you and I like a pretty bunch of flowers may be entirely different to a botanist. I’m not at all sure that bees care one way or another. JK
