Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata. [2] The male has a blue abdomen that is often pale and usually has a greenish thorax. The female is a very ...
Eggs of the adult beetle are laid on a surface. Larvae burrow into the material of the commodity surface they are laid upon. Larvae have an elongated shape, marked by three pairs of jointed legs. The head, first thoracic segment, and part of the last abdominal segment are sclerotized, while the remaining segments have a soft-skinned, marbled ...
The antennae of both sexes are dark brown to black. The male's antennae are two-thirds its body length, and the female's are one-half. The legs are reddish brown. The full grown larvae are legless, white, and robust, growing to roughly 25 mm (0.98 in) long.
Over the ensuing months, the female migrates to connective tissue or along bones, and continues to develop. [6] About a year after the initial infection, the female migrates to the skin, forms an ulcer, and emerges. When the wound touches fresh water, the female spews a milky-white substance containing hundreds of thousands of larvae into the ...
A few species feed on larger vertebrate carcasses. Flesh fly maggots occasionally eat other larvae, although this is usually because the other larvae are smaller and get in the way. Flesh flies and their larvae are also known to eat decaying vegetable matter and excrement, and they may be found around compost piles and pit latrines. [3]
Sarcophagidae larvae are white or pale yellow, cylindrical, and tapered anteriorly. All segments beyond the first have anterior and posterior bands of hairs. The mandibles are usually strong and curved, resembling a hook. Posterior spiracles are sunken in, which is a characteristic that can be used to distinguish between flesh fly and blow fly ...
Larvae typically have four instar stages with three moults between them. [42] The larva eventually transitions into a pupa; which involves the development of a hunch, the fusion of the legs to the body, and the attachment of the posterior to the surface. [7] [20] [42]
Monochamus scutellatus, commonly known as the white-spotted sawyer or spruce sawyer or spruce bug or a hair-eater, [1] is a common wood-boring beetle found throughout North America. [2] It is a species native to North America.
