The great red damselfly is often the first damselfly to emerge, usually in April or May. Adults can be found until September, according to locality. [4] Immature adults mature in about two weeks. Mating occurs in vegetation. [6] The female during the laying of eggs is accompanied by the male, [6] she immerses into the water only the abdomen ...
Similar to their close relative, the damselfly can be determined by the noticeably large eyes disproportionate to their head, alongside distinct veins on the wings. [ 10 ] Male Xanthocnemis zealandica measure roughly 24-38mm in length, with a wingspan of 15-23mm, whereas the female zealandica tends to be slightly larger, measuring around 28 ...
Pyrrhosoma elisabethae Schmidt, 1948 – Greek red damselfly Pyrrhosoma nymphula ( Sulzer , 1776) – large red damselfly Former congeners Pyrrhosoma latiloba Yu, Yang & Bu, 2008 and P. tinctipenne (McLachlan, 1894) are now placed in genus Huosoma Guan, Dumont, Yu, Han & Vierstraete, 2013 .
Pyrrhosoma elisabethae, the Greek red damselfly, is a species of damselfly in the family Coenagrionidae. The damselfly finds its habitat in rivers. It is found in Albania and Greece. It is threatened by habitat loss.
In a study of the European common blue damselfly, every adult insect was infected at the height of the flying season. When present in large numbers, these parasites can cause death by blocking the gut. [22] Water mites Hydracarina are often seen on the outside of both nymphs and adults, and can move from one to the other at metamorphosis. [22]
Adults are exceptionally large for damselflies, with wingspans as high as 19 cm (7.5 in.) reported for Megaloprepus [6] and body length up to 13 cm (5.1 in.) for Pseudostigma aberrans. [7] The pterostigma —a thickened, pigmented cell found on the leading edge of the wing in other odonates —is either missing or else modified into a ...
What it looks like: The most recognizable reaction on this list is the bullseye rash—a large, red, target-like rash that signals the early stages of Lyme disease from the bite of an infected ...
Megaloprepus lays its eggs in the water that collects in holes in trees by depositing the eggs within the wet bark.These plant-borne bodies of water, known as phytotelmata, may form in a living tree when a branch breaks off or a burl rots and fills with water, in buttresses of some trees that hold water including the common Pentaclethra macroloba, or indentations in a trunk may fill with water ...
