Sword-bearing Conehead

My mothing nights find more than moths. Beetles, bugs, flies, wasps, spiders, and crickets, even snakes and frogs, are frequent visitors to the porch light. The latest non-lepidopteran to make an appearance is the sword-bearing conehead (Neoconocephalus ensiger). It is a new addition to my insect checklist and is one of five species of Tettigoniidae (Katydids) that I’ve identified from here.

The sword-bearing conehead is a large insect with males growing 4.5 to 5.5 cm, and females 5.2 to 6.4 cm. The head is conical with the sides pinched-in and black below. The body’s lower surface is edged in black. The stridulatory vein, which is used to make the call song in males, is long and weakly swollen. The ovipositor is blade-like and nearly the length of the body hence the name “sword-bearing”. Two color forms, green and brown, exist.

The call song of the sword-bearing conehead is a series of rapid tsst-tsst-tsst sounds. At higher temperatures the call song is faster. Singing begins at dusk and may continue all night if temperatures are warm. Singing Insects of North America (SINA) and Songs of Insects have recordings of this species and others on their websites.

Sword-bearing conehead is common across much of the eastern and north-central US and ranges as far north as Manitoba, Ontario, Quebec, and New Brunswick in Canada. Habitat includes damp grassy areas, roadsides, and weedy areas where they feed on grasses and sedges including the flowers and developing seeds.

A tremendous increase

Digrammia mellistrigata
One of the latest additions to the checklist is Digrammia mellistrigata (yellow-lined angle) a moth in the Geometridae (inchworms).

Since I last posted on the moth species diversity (a very long time ago) the list has gone from 270 to 761 species and will very likely continue to grow until winter puts a stop to insect activity outdoors. Some species were to be expected as they are common and widespread but there have been nights and a few days with interesting surprises. Eventually, the number of new additions will level off and then fall as the actual number of species is approached. But for the next year or two, about 50 new species will probably be added each season. Just in 2022 I’ve added 50 more species with July being the best month with 21 species. I’m not going to go through the whole list of new additions but below is a small sample of my favorites from the last few years. In some future posts I’ll be covering some unusual species occurrences while others will cover groups such as new Geometridae or new Crambidae I have found.

I think it’s about time to revive this blog

Well, I’ve been away for quite some time now. A lot has been happening here where I live and my life has gone through some changes. The biggest change is that I have officially retired. This happened right around the time of the COVID lockdown. Great timing, right?

This past July I finally got to take that vacation I was going to do in 2020 car camping and hiking in the Superior National Forest. That is one of the places where I used to work but this time the pace was relaxed and it didn’t matter if everything on the agenda was completed or not.

A micro-moth I found on the Superior Hiking trail in Lake County, Minnesota. It might be Landryia impositella or maybe a species of Scythris. Whatever species it is this moth is nectaring on big leaf aster in a sugar maple/paper birch forest.

I’ve also been doing a lot of exploring where I live and have found many more species of moths, one of my latest obsessions, as well as lichens, fungi, plants, and other living things. Back when I stopped posting the moth checklist was at about 470 species. Now, it is at 763 species and will probably go even higher before the winter weather arrives in late October.

Apantesis phalerata (harnessed tiger moth) one of the new moth species discovered this year at my porch light. Its presence marks a significant range extension north.

I’m building up the checklists on other insect species, too. While not as large (yet) as the moth lists they have been steadily growing. My focus is on bugs, beetles, wasps, and bees which is enough for now. Down below is one example of the new beetles on the checklist, Chlaenius tricolor (ground beetle), which under certain light conditions has a metallic iridescence. More will be coming soon.

I’ll be away from my desk…

Metanema inatomaria a species seen last summer on warm humid nights.

 

…during much of July and so will be posting a little less frequently. But summer has arrived and brings with it a new group of moths that love the hot and humid weather. Here are five of the seventeen new moths plus one returning visitor that showed up at my porch light over the weekend. I’ll be writing about these species later in August. There are already a few in the works on the moths Habrosyne scripta (almost done!), Oreta rosea, Phlogophora iris, Campaea perlata, and Monopis spilotella seen this year and last year.
