Below is a compilation of a few tiny creatures I’ve come across in the last week or so. All photos were taken using a macro lens on my iPhone. This is a carpet beetle in the genus Anthrenus, likely Anthrenus verbasci, in the flower of a China girl holly. Adults of this species eat pollen, so it’s a logical place to find this one. For those unfamiliar with the scale of holly flowers, this beetle is tiny – only a…
On a recent walk at Mass Audubon’s Tidmarsh Sanctuary, I noticed something out of the ordinary attached to the stem of a shrub a little ways off the trail. It sort of resembled a brown dried leaf, but there was something just different enough about it that it caught my attention. Closer inspection revealed that it was a cocoon of some sort. I immediately had two conflicting thoughts: 1) I want to cut it open so I can see what’s…
American dagger moths (Acronicta americana) are a fairly nondescript gray moth, perfect for camouflaging itself against mottled tree trunks during the day (see this BugGuide link for pictures of adult American dagger moths). The caterpillar of the species, on the other hand, is one of the fluffiest larval lepidopterans I’ve ever encountered. It is covered in dense hairs, called setae, which are yellow in younger instars and turn white as the caterpillar ages. There are also longer pairs of black…
I love warm rainy nights in December. Not because I particularly like rain, but because I love how winter moths (Operophtera brumata) emerge seemingly out of nowhere, to take advantage of the warmer weather. In fact, they’re one of very few Lepidopterans in the temperate region that are active in the late fall and early winter. On nights like we had this weekend, with light rain and temperatures close to 50 degrees, they can be so numerous that they remind…
While exploring Johns Pond Park in Mashpee a couple weeks ago, I noticed one pine tree that was covered in hardened sap blobs, each with a distinctive circular hole leading back into the tree’s trunk. At the time I attributed the condition to a pest infestation, but had no way of identifying the specific pest. Thanks to some asking around and sharing the photos of the sap blobs with a professional entomologist, I now know that these “wounds” were caused…
