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 ...
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 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.
Trichogramma is a genus of minute polyphagous wasps that are endoparasitoids of insect eggs. [1] Trichogramma is one of around 80 genera from the family Trichogrammatidae, with over 200 species worldwide. [2] [3] [4]
Eclosion is the process in which an adult insect emerges from its pupal case, or a larval insect hatches from its egg. In holometabolous insects, the circadian clock regulates the timing of adult emergence. The daily rhythm of adult emergence in these insects was among the first circadian rhythms to be investigated.

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 ...
