Don’t they make everything bigger in this state? I avoided it, as I was afraid it’d spear me deeply! Over the years, I heard that it wasn’t a mosquito.
A few weeks ago, I spotted a humongously long-legged bug on my back storm door. I was able to take only one picture before it flew off! I estimated it to be at least 4 inches top to bottom, about the size if I held my thumb and forefinger apart as a guide. This bug, as I've been told, is a crane fly, which, incidentally, is called a daddy longlegs in UK.
Actually, I had been planning to write about daddy longlegs, the 8-legged kind. I’ve queued it up for the next article.
On LinkedIn, I requested help with IDing the bug, posting a cropped and color/contrast modified image. Two people piped up and declared it a crane fly, and pasted a couple of links. Pinning down my exact specimen’s category became really difficult. Sooooo many members in the crane fly group! The Bug Guide search for “crane fly” yielded loads of hits.
From using BG and other bug links, I’ve settled that my bug is in Arthropods (Arthropoda) > Hexapods (Hexapoda) » Insects (Insecta) > Flies (Diptera) > "Nematocera" (Non-Brachycera) > Crane Flies (Tipulomorpha) > Large Crane Flies (Tipulidae) > Tipulinae > Tipula.
Because I was able to shoot only one picture, I wondered how to gauge the size. I decided to try to replicate the photo’s background and include a measuring stick. A few days of shooting, and I came up with the composite with a superimposed reduced-opacity measuring stick, then cropped it. I’d say the crane fly measured at least four inches leg tip to leg tip, as my upper image indicates. The following pixstrip shows the integration of two main images into one.
I think my bug resembles the Tipula disjuncta crane fly by Gayle and Jeanell Strickland. Although my bug looks ghostly white, I’m not sure how the lighting, flash-on, and my distance might have affected how it photographed. And I wish it’d been in better focus.

From Entomology Today's "Mosquito Hawk? Skeeter Eater? Giant Mosquito? No, No, and No"
They have a narrow body with two long and slender wings, as well as six stilt-like legs that can be twice as long as the body. Crane flies are diverse in wing pattern, color, and size.From "The Crane Fly vs. The Mosquito! A Case of Mistaken Identity: A Crane Fly is not a Giant Mosquito!"
It is important to differentiate between these two bugs because mosquitoes transmit diseases like West Nile virus, encephalitis and Malaria, killing millions of people worldwide each year. Crane flies cannot bite and they do not carry diseases.SHERDOG “crane fly and mosquito” comparison info with diagram
From Wikipedia's "Crane fly" site
Adult crane flies have very long legs and a long, thin abdomen. It is very easy to accidentally break off their delicate legs when catching crane flies. Their thin legs and abdomen may help them to escape from birds who try to eat them. Females have larger abdomens in comparison to the males. The female abdomen also ends in a pointed ovipositor that looks a bit like a stinger. Crane flies cannot sting.“Crane Flies - Infraorder Tipulomorpha”
