We’ve had a few cool days in Raleigh so far this fall, but it’s been quite warm overall. This means that a lot of insects have been out later than usual, in some cases quite a bit later than usual. A couple of weeks ago, I had lunch at a nearby arboretum, just to get outside in a pretty place for a while, and I came across this field of cosmos:
That photo was taken on November 10th, so I was very surprised to come across so many blooming flowers! Several other flowers were also in bloom, so there were quite a few different insect species making use of the nectar. There were, of course, many bees, including honey bees:
There were also at least three different species of bumble bee, though I’ll admit that I am terrible at figuring out which species is which:
Most of the bumble bees I come across in my area are the common eastern bumble bee, and I suspect this one is as well, but I couldn’t say for sure.
On the same flowers, I came across a few butterflies. I hardly ever see cabbage whites, so I was excited to see this one:
I know they’re a pest species and a lot of people really dislike them. And yes, they did once eat all of the broccoli I planted in my garden. However, they’re really beautiful and they’re just doing what they do when they eat my broccoli, so I like them anyway. :)
There were tons of these checkered skippers in the field of flowers:
I don’t know why, but I rarely see these at the museum field station where I work, even though it’s just a mile or so away from the arboretum where I took these photos. There are tons of them at the arboretum though, almost every time I go! I spotted at least two other skippers the same day, but only got a photo of this one:
I believe this is a fiery skipper, but I’m not 100% sure about my ID. What can I say? Butterflies are not my best group as I just took a real interest in them recently, but I’m working on getting better. Skippers are harder to ID than a lot of other groups, so they’re my weakest group and probably will remain so for a while.
You might have noticed the cucumber beetle in the photo with the honey bee. Once I saw one, I started looking for them and found dozens more, about one per 2-3 flowers:
Apparently they really like these flowers. They’re an agricultural crop pest, so it made me wonder if all the holes in the petals I was seeing were caused by the beetles. A lot of the most heavily damaged flowers had the beetles on them, but that could just be coincidence. There were a lot of beetles on a lot of flowers!
I spent a long time watching the insects in this field of flowers, but I saw several more as I walked back to my car. There were more butterflies out, including this common buckeye (one of my favorite butterflies!):
… and this American lady:
I didn’t manage to get a photo of the swallowtail that was flying around as it wouldn’t sit still long enough, but there was one eastern tiger swallowtail floating around the area. There were also a ton of hover flies, of multiple species. This one:
… and this one:
… seemed like particularly good bee mimics, about the same size and had rather similar behavioral patterns as honey bees. In fact, a pair of women came up to this planting while I was there and said, “Wow! Look at all those bees!” I, being the annoying person that I am sure I sometimes am, couldn’t let that pass, so I told them that a lot of what they thought were bees were actually flies and pointed out the differences. Not sure they really wanted the entomological lesson right then, but I just can’t help myself sometimes.
Fall has been coming on a lot more slowly in my area than normal this year, so I’ve been surprised more than once by the things that are still visible that are usually gone by now. I found a monarch caterpillar a few days ago and there are still a few milkweed plants alive! A few years ago, I remember seeing a monarch adult on November 2 and thinking it was terribly late, but this year I’m still seeing caterpillars. Strange, and a little disturbing that it’s so warm so late, but I’m going to enjoy seeing insects out as long as they last – and welcome winter with open arms when it finally arrives.
