Introducing: The Cranefly

I found this fellow perched on the outside of my sliding glass door this

morning. I thought it was a male mosquito since they are much larger than their female counterparts (the ones that bite us). However, a search in Bug Finder revealed it to be the cranefly. You can read more about it on Insect Identification.

You gotta love those googly eyes!

Insectorama: Second Season

Falmouth Audubon: Google Earth photo


I went out to the Gilsland Farm (Falmouth Audubon), yesterday. It was a good bug photography day–overcast, light wind and about 75° F. As I walked along

many of the field and woods paths I wasn’t finding too much going on in the bug world. Perhaps that’s because we’re living during the insect apocalypse (see earlier posts).

Unexpectedly, I found more in the way of larger animals (and a former eagle’s nest). Unfortunately, these images aren’t super sharp as my camera was not set up for this type of

photography. However, given that I was rather close, you can see how these animals have come to see their environment as safe.

Oh, and one last thing for you peony lovers, the garden looks like it is about ten days away until full bloom.

Winter Moths on Peaks Island

The other night while driving to my friends’ on Peaks Island I saw thousands of winter moths in my headlights. When I returned home there were dozens on the outside wall by my lighted front door. I told my friends about this who said that southern Maine is loaded with these pests that became established in the area around 2012.

A little research on my part found that they are native to Europe and the Near East; they were inadvertently introduced into Canada in the 1930s. They have no predators in North America and are now established in New England and the Pacific Northwest.

They are highly destructive of deciduous trees, as they eat the leaves during the caterpillar stage of their life cycle. The tree will die if it is infested with this caterpillar for several years in a row.

Remedies to limit these moths have included spraying plants in the spring before the ambient temperature reaches 55 degrees Fahrenheit, and tying sticky strips around tree trunks so the wingless female cannot climb up to lay her eggs in the tree’s crown. However, a more effective strategy is to release its natural predator, a wasp (Agrypon flaveolatum) and a fly (Cyzenis albicans). The latter has worked particularly well recently in Massachusetts, but not so well in the Portland, Maine area where there have been at least two major fly releases, as reported in the Bangor News and by the Maine Department of Agriculture, Conservation & Forestry.

The infestation of winter moths does not seem to be related to climate change, but rather global shipping and travel. You can read more about this pest in a Maine Department of Agriculture, Conservation & Forestry document.

The Great Black Wasp

Black Wasp

Living underground, the iridescent Great Black Wasp pollinates flowers while feeding itself, and removes plant pests while feeding its young making it a great friend to gardens and fields. They keep the grasshopper and cricket

populations under control. This rather unaware grasshopper on the right is feeding in the same bush as the wasps.

You can see my complete collection to date at Insectorama.

Is There a God?

Praying Mantis

Apparently the Praying Mantis thinks so. Or maybe it’s poised to grab an insect (or Humming Bird). Whatever the reason we found one near my sister’s family home in Connecticut. The various Mantis’ are humanity’s friends since

they eat many of those insects that eat our crops. Load your garden up with them. They are members of the cricket/grasshopper family. You can read more about our Mantis friends at It’s Nature.

The “Deadly” Scorpionfly

Well, it looks dangerous, but it isn’t. It only looks a bit like a scorpion. I found this guy in the reeds along side the Oatka Creek. Found in the eastern U.S., the “stinger” is the male’s copulatory organ. They feed on dead insects. You can see more of what I’ve photographed at Insectorama. More insects to come!

Emerging Insects

Recall two of my recent posts, The Bugs Are Coming, where I discussed the bugs that are bad for us, and Where Have All the Insects Gone?  . . . , where I reported that many of the good insects are disappearing. Well, things are starting to gear up with the bugs now emerging. It has been a bit of a late start given the lower than average temperatures we have been experiencing here in the northeast.

Margined (Burying) Carrion Beetle

The first and third photos were taken in Connecticut in April. I found the Carrion Beetle on a driveway.  It is found mostly in farm and other rural areas. The IUCN (International Union for Conservation of Nature’s Red List of Threatened Species) categorizes this species as critically endangered, likely due to the use of pesticides, and land “development,” among other factors.

My next subject is the Ebony Jewelwing. I will leave you to guess why it is so

Ebony Jewelwing

named. This species is categorized by the IUCN as of least concern, due to its stable population.  It is found mostly along lakes and streams. I photographed several of these back in 2011 in western New York and present one here since the photo quality is excellent.

Chocolate Dun

The Chocolate Dun is a Mayfly usually found in the pools of fast running streams and rivers with clear rocky bottoms. However, this one was on a window of a glassed in porch. They are not listed in the IUCN data. Fisherman refer to the adults as spinners. You just have to love the googly eyes of these winged insects. “All the better to see you with.”

I photographed the Jewelwing in strong sunlight using a Canon 60D with a Canon 100-400mm lens @ 390mm and exposed at ISO 500, f/11 @ 1250/sec. The current and future insect photos will be shot using a Canon 7D II with a 15-85mm Canon lens at 85mm. A ring flash attached to the lens will allow manual exposures @ ISO 100, ~ f/11 @ 125/sec., enabling me at get sharp images with relatively good depth of field on the insects.

 

Coming Attractions


Starting in later April I will be bringing you photos of various insects from around the Northeast. Oooh! Insects you might wince, why insects? I know, we are not crazy about them. They look kind of scary, they bite us, and sometimes get into our food supply. What’s to like? The reality is they are part of our ecosystem. They provide food for birds, reptiles and others (and perhaps us in the future as we cut back on farm animals due to their intense use of resources, not to mention the methane flatulence of cattle). They are an important part of earth’s ecosystem.

As I did several years ago with my bird photographs, I will give a brief description of each bug and whether it is on the endangered list. In the meantime here are a couple of photos to warm you up to these “cute” little creatures. I took these photos in the early 70s. I’ll be using my digital camera for the upcoming color photos so they will be much sharper.
