Marava arachidis

Identified through morphological examination and molecular DNA barcoding (COI gene), with approximately 1.55% sequence divergence from reference specimens. As a member of Spongiphoridae, it lacks the prominent forceps of some other earwig families, though specific diagnostic features for field identification are not documented in available sources.

Found in stored animal rations, bakeries, bran, and water houses of imported organic materials. Uses fennel plants (Foeniculum vulgare) for shelter and climbs stems to feed on nectar. Occurs in tropical regions and has established populations in temperate areas through human-mediated transport.

Cosmopolitan distribution with established populations in Africa, Australia, the Caribbean, Europe, Northern Asia (excluding China), North America, South America, and Southern Asia. First recorded in Egypt from Beni-Suef. Present in California since 1920. Sporadic occurrences in Britain and northern Europe.

Feeds on aphids and fennel nectar. Laboratory studies demonstrate consumption of tick eggs and larvae (Rhipicephalus annulatus), with mean predation of 18.64 ± 11.18 eggs and 12.32 ± 9.07 larvae per 24 hours at 1:10 predator-prey ratio.

• Foeniculum vulgare - shelter and nectar sourcefemales lay eggs on leaves; used as climbing structure
• Rhipicephalus annulatus - predatoreggs and larvae consumed in laboratory conditions
• Aphidoidea - predatoraphids reported as prey based on literature citation, not direct observation

Ovoviviparous: females retain well-developed embryos encased in thin but complete egg envelopes until a few minutes before hatching. Laboratory rearing is reportedly easy with available artificial diets.

Exhibits density-dependent predation on tick eggs and larvae, with consumption rates increasing linearly with predator density. Climbs vegetation to access nectar sources. Predation includes breaking eggs and killing larvae beyond immediate consumption.

Potential biological control agent for tick populations, particularly Rhipipicephalus annulatus. Functions as a generalist predator in laboratory settings, though field efficacy remains unverified.

Recorded as a pest or inhabitant of stored food facilities including bakeries and animal ration storage. Investigated for biological control applications against cattle ticks. Easily reared in laboratory conditions for research purposes.
