The egg case is very smooth and lacks external fibrous material. [1] This egg case can be easily identified from all others in that it is the only one to have a steep ridge; giving the case a convex shape. [1] The keel on the egg case is considered very broad; representing 30–33% of the width of the egg case. [1]
Entomological evidence collection is the process of collecting evidence based on insect clues used in criminal investigations.If evidence is not carefully preserved at a crime scene after a death, it may be difficult or impossible for an entomologist to make an accurate identification of specimens, if for example, all morphological characteristics are not preserved.
Digital automated identification system (DAISY) is an automated species identification system optimised for the rapid screening of invertebrates (e.g. insects) by non-experts (e.g. parataxonomists). It was developed by Dr. Mark O'Neill during the mid-1990s. Development was supported by funding from the Darwin Initiative in 1997 [1] and BBSRC. [2]
The male is smaller (wingspan up to 9 mm) and more slender with less distinct markings. The reduced mouthparts suggest this species does not feed as an adult. The female lays up to 200 tiny pale blue eggs in sheltered places. The larva constructs a protective case from silk and camouflages it with other materials such as soil, sand and insect ...
Oothecae are made up of structural proteins and tanning agents that cause the protein to harden around the eggs, providing protection and stability. [1] The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive ...
Females tend to deposit egg masses at relatively few sites, resulting in grouped egg masses. [16] One to two weeks after oviposition, the eggs hatch and the first instar larvae either fall directly into the stream or if not, immediately search for water. There the larvae live for up to five years, going through 10-12 instar molts. [9]

The egg stage in most insects is very short, only a few days. However, insects may hibernate, or undergo diapause in the egg stage to avoid extreme conditions, in which case this stage can last several months. The eggs of some types of insects, such as tsetse flies, or aphids (which are hemimetabolous), hatch before they are laid.
