Moreover, there is a non-significant of variation between all stages in the gender of cycad blue butterfly in description details here, but the adult male was more densely blue or violet than adult female, Similarly, it was described by Kehimkar (2008); Batt et al (2019) and Abu-shall and Tawfeek (2015).

“…In the present work, cycad butterfly, C. pandava in order Lepidoptera belonging to family Lycaneidae and subfamily Polyommatinae. The genus of Chilades was widely distributed on a varied range of ornamental plants, but C. pandava was restricted to be on the two palm species, Cycas and Zamia, in Egypt as that reported by Batt et al (2019) and Abu-shall and Tawfeek (2015). Also, observed in other countries especially tropical regions including Guinea (Tennent, 2014), Taiwan, India, China, Sri Lanka and Southeast Asia (Igarashi and Fukuda, 2000;Hsu et al, 2002).…”

The serious blue butterfly, Chilades pandava -Horsfield, 1829- (Lepidoptera: Lycaenidae) is consider one of the main destructive insect pests for ornamental palms Cycas and Zamia. Biological and morphological measurements were carried out of C. pandava stages reared on Cycas revoluta (Cycadaceae) and Zamia encephalartoides (Zamiaceae). In description details, non-significant variations were recorded between the two gender of cycad blue butterfly in the obtained data, but the male adult was more densely blue or violet than female adult. By the aid of SEM, C. pandava all stages were distinct by long and thick hairs covered all the body. The morphometric characters namely, length, width and venation of wings, body length, forewing, hindwing could be as a guide for taxonomic discrimination. The data showed that the life cycle duration of C. pandava was ranged between 20.64 to 21.7 days. The developmental periods of different C. pandava stages are slightly higher on zamia than cycas palms. This investigation detected that a high survival rate was found on Cycas palms (86%) than the survived rate recording on Zamia palms (82%). In the present study, the described morphometric characters could be used as a guide for taxonomic discrimination of this pest. Consequently, this study added a valuable knowledge about C. pandava to have sound decisions for proposal of its management and conservation in Egypt.

Deudorix livia (Klug, 1834) (Lepidoptera: Lycaenidae) is one of the most serious lepidopteran insect pests attacking pomegranate fruit around the world, including Egypt (Assiut Governorate, Upper Egypt). To create an effective program (IPM) to control such harmful pests, accurate identification of the pest morphology and genetic structure is essential. Studies on the morphogenetics of this pest are scarce. So, the goal of this research is to identify it both morphologically and genetically. Pomegranate butterfly immature stages were collected from infested pomegranate fruits and reared in the laboratory until the adult's emergence. By using light and scanning electron microscopy, some morphological structures of males and females were studied. DNA was extracted from the legs of a pomegranate butterfly adult. Also, PCR was conducted by using the mitochondrial CO1 gene for sequencing and phylogenetic tests. The results show that the body scales are a mixture of dark and light gray on the dorsal side and white on the ventral side in both sexes. The average male body length (BL) was 11.674 ± 0.299 mm and was 11.458 ± 1.001 mm for the females. The wing venation is similar in both sexes. For the first time, a partial sequence of the mitochondrial CO1 gene in D. livia was deposited in GenBank (MW463927).

The eyes have it: dim-light activity is associated with the morphology of eyes but not antennae across insect orders

The perception of cues and signals in visual, olfactory and auditory modalities underpins all animal interactions and provides crucial fitness-related information. Sensory organ morphology is under strong selection to optimize detection of salient cues and signals in a given signalling environment, the most well-studied example being selection on eye design in different photic environments. Many dim-light active species have larger compound eyes relative to body size, but little is known about differences in non-visual sensory organ morphology between diurnal and dim-light active insects. Here, we compare the micromorphology of the compound eyes (visual receptors) and antennae (olfactory and mechanical receptors) in representative pairs of day active and dim-light active species spanning multiple taxonomic orders of insects. We find that dim-light activity is associated with larger compound eye ommatidia and larger overall eye surface area across taxonomic orders but find no evidence that morphological adaptations that enhance the sensitivity of the eye in dim-light active insects are accompanied by morphological traits of the antennae that may increase sensitivity to olfactory, chemical or physical stimuli. This suggests that the ecology and natural history of species is a stronger driver of sensory organ morphology than is selection for complementary investment between sensory modalities.
